Woodworking may sound complicated and daunting, but there are plenty of plans online that are simple, fast and budget-friendly. These projects are perfect for a rainy Saturday afternoon, and many are easy enough for you to build with kids. Once you decide on a project, simply search online for free woodworking plans, check out the supply lists, purchase your supplies and start working on your project. For a few ideas to get you going, check out these 10 simple and fun DIY woodworking projects:

Shoe Organizer

For a quick, easy project that you can complete in about an hour, consider making a shoe organizer. If you have little floor space, a wall-mounted organizer works well. Otherwise, there are plenty of plans available online that include a bench on top for seating and shelving below for shoe storage.

Top 5 physics experiments you can try at home

October 17, 2022 By Emma Vanstone Leave a Comment

Physics is key to understanding the world around us. While some aspects may seem tricky to understand, many fundamental physics concepts can be broken down into simple concepts, some of which can be demonstrated using basic equipment at home.

This list of 5 physics experiments you can try at home is a great starting point for understanding physics and hopefully a source of inspiration for little scientists everywhere!

1. Archimedes and Density

The story behind Archimedes’ discovery of density is that he was asked by the King of Sicily to work out whether a goldsmith had replaced some gold from a crown with silver. Archimedes needed to work out if the goldsmith had cheated without damaging the crown.

The crown weighed the same as the gold the King had given the goldsmith, but gold is more dense than silver so if there was silver in the crown its density would be less than if it was pure gold. Archimedes realised that if he could measure the volume of the crown he could work out its density, but calculating the volume of a crown shape was a tough challenge. According to the story, Archimedes was having a bath one day when he realised that the water level rose as he lowered himself into the bathtub. He realised that the volume of water displaced was equal to the volume of his body in the water.

Archimedes placed the crown in water to work out its density and realised the goldsmith had cheated the king!

Density Experiment

One fun way to demonstrate density is to make a density column. Choose a selection of liquids and place them in density order, from the most dense to the least dense. Carefully pour a small amount of each into a tall jar or glass starting with the most dense. You should end up with a colourful stack of liquids!

2. Split light into the colours of the rainbow

Isaac Newton experimented with prisms and realised that light is made up of different colours ( the colours of the rainbow ). Newton made this discovery in the 1660s. It wasn’t until the 1900s that physicists discovered the electromagnetic spectrum which includes light waves we can’t see, such as microwaves, x-rays waves, infrared and gamma rays.

How to split light

Splitting white light into the colours of the rainbow sounds tricky but all you need is a prism . A prism is a transparent block which is shaped so light bends ( refracts ) as it passes through. Some colours bend more than others so the whole spectrum of colours can be seen.

If you don’t have a prism you can also use a garden hose! Stand with your back to the sun and you’ll see a rainbow in the water! This is because drops of water act like a prism.

3. Speed of Falling Objects

Galileo’s falling objects.

Aristotle thought that heavy objects fell faster than lighter objects, a theory that was later disproved by Galileo .

It is said that Galileo dropped two cannonballs with different weights from the leaning tower of Pisa which hit the ground at the same time. All objects accelerate at the same rate as they fall.

If you drop a feather and a hammer from the same height the hammer will hit the ground first, but this is because of air resistance!

If a hammer and feather are dropped somewhere with no air resistance they hit the ground at the same time. Commander David Scott proved this was true on the Apollo 15 moonwalk!

Hammer and Feather Experiment on the Moon

Brian Cox also proved Galileo’s theory to be correct by doing the same experiment in a vacuum!

While you won’t be able to replicate a hammer or heavy ball and feather falling you can investigate with two objects that are the same size but different weights. This means the air resistance is the same for both objects so the only difference is the weight.

Take two water empty water bottles that are the same size. Fill one to the top with water and leave the other empty. Drop them from the same height. Both will hit the ground at the same time!

4. Newton’s Laws of Motion

Sir Isaac Newton pops up a lot in any physics book as he came up with many of the laws that describe our universe and is undoubtedly one of the most famous scientists of all time. Newton’s Laws of Motion describe how things move and the relationship between a moving object and the forces acting on it.

Making and launching a mini rocket is a great way to learn about Newton’s Laws of Motion .

The rocket remains motionless unless a force acts on it ( Newton’s First Law ).

The acceleration of the rocket is affected by its mass. If you increase the mass of the rocket its acceleration will be less than if it had less mass ( Newton’s Second Law ).

The equal and opposite reaction from the gas forcing the cork downwards propels the rocket upwards ( Newton’s Third Law ).

4. Pressure

Pressure is the force per unit area.

Imagine standing on a lego brick. If you stand on a large brick it will probably hurt, if you stand on a smaller brick with the same force it will hurt more as the pressure is more!

Snow shoes are usually very wide, this is to reduce the pressure on the snow so it sinks less as people walk on it.

Pressure equation. Pressure is force divided by area

Pressure and Eggs

If you stand on one egg, it will most likely break. If you stand on lots of eggs with the same force you increase the area the force is applied over and therefore reduce the pressure on each individual egg.

That’s five easy physics experiments you can do at home! Can you think of any more?

How to Do DIY Physics Experiments That Will Impress Everyone

Marcia Wendorf

Science experiments are a great way to introduce kids, or the kid in all of us, to fundamental scientific principles . Here are some cool physics projects that you can do at home.

For any of these experiments, it's a good idea for an adult to supervise children, to always wear safety glasses, and if working with fire, to have a fire extinguisher handy.

Amaze Your Friends With a Fireproof Balloon

For this experiment, all you need is a balloon and a candle. Fill the balloon three-quarters full with water, and top it off with air by blowing the balloon up as far as it will go. Tie it off.

Light the candle, then slowly lower the balloon over it. Behold, the balloon won't pop!

This is due to water's incredible ability to absorb heat . The water in the balloon disperses the heat generated by the candle, and keeps the latex of the balloon from getting hot enough to break. But, when the water in the balloon can't absorb any more heat from the candle, the balloon will burst, and you'll probably get a little wet.

The Lava Lamp

From your kitchen, grab a bottle of vegetable oil, food coloring, some salt, and either a large glass or a glass jar.

Fill the glass container 2/3rds full of water and fill the remainder with vegetable oil. Add some food coloring, then slowly pour one teaspoon of salt into the container. Watch as beautiful colored orbs of oil gently fall to the bottom of the container.

At first, the oil will stay at the top of the container because oil is lighter than water . The key to making the oil fall to the bottom is the salt, it binds to the oil, making it heavier than the water. However, once the salt dissolves in the water, the oil will rise again to the top of the container. Groovy!

Grow Some Crystals

This classic experiment takes few days to complete, but it's well worth the wait.

You'll need some distilled water, salt or Epsom salts, a piece of wire or a pipe cleaner, and a glass container. First, heat the distilled water to a point just below boiling. Fill the glass container at least half full with the hot water. Add enough salt or Epsom salts to the water to create a saturated solution (the point when no more salt will dissolve in the water) and stir well.

Make a loop in the wire or pipe cleaner and lower the wire into the mixture. Place the container in a warm spot and wait. After a few days, you should see spectacular crystals forming on the loop of the wire.

This experiment works because of the temperature change of the water , and the solubility , the capability of the salt to be dissolved. As the water cools, the solubility of the solution decreases, and the salt precipitates out of the solution and onto the wire to form crystals.

Build a Popsicle Stick Catapult

To build this mini-catapult, you'll need at least 10 large popsicle sticks, a bunch of rubber bands, a pair of scissors, and some marshmallows for cannonballs. Marshmallows for cannonballs? How dastardly!

Stack eight popsicle sticks, and hold them together with rubber bands at each end. On the two remaining sticks, use the scissors to make a small notch on each side of the stick. Place them together and use a rubber band to hold the sticks together at the notch.

Then, pull the two sticks slightly apart and slide the eight-stick bundle between them. Steady your new catapult with one hand, and use your other hand to place a marshmallow on the top stick. Pull it back and release to fire!

You can also bind a plastic spoon with a rubber band to the top stick to make a bucket for holding your cannonballs. The castle walls will fall!

Make a Prism

You can make a rudimentary prism with just distilled water and clear gelatin. Empty a packet of gelatin into a pot and add only half the amount of water listed in the gelatin package instructions.

Place the pot on the stove, and as the pot warms, stir the gelatin gently to dissolve it. After the gelatin has dissolved , place the mixture into a small container and let it sit for 30 minutes to cool.

Cut the gelatin into squares or prism shapes, which is half of a square or rectangle cut on the diagonal. Shine a flashlight through the gelatin to see the light broken up into its spectral colors . You can also shine a laser pointer through the gelatin to see the light bend.

Create a Whirlpool

You can make a cool whirlpool by using two empty 2-liter soda bottles, a metal washer that has an opening smaller than the mouths of the bottles, and duct tape. Fill one of the 2-liter bottles, 2/3 full of water.

Place the washer on top of the filled bottle, and place the empty bottle upside down on top of the washer. Tape the two bottles together and quickly flip the bottles. You should see a water vortex (aka whirlpool) form as the water from the top bottle flows into the bottom bottle.

The vortex forms because the water spins faster around the edges of the bottle, creating a hole in the middle. This vacuum then fills with air from the bottom bottle, and water from the top bottle flows around it.

Build a Potato Battery

For this experiment, you'll need a potato, a galvanized nail, a piece of copper sheeting, or a copper coin such as a penny, two alligator clip leads with clips on both ends, and a voltmeter .

Galvanized nails have a zinc coating, and they can be purchased at any hardware or home improvement store. Be sure to use a fresh potato because the experiment depends on the liquid inside the potato.

Stick the galvanized nail into the potato, making sure that it doesn't go all the way through. About an inch (2.5 cm) away from the nail, stick in the penny.

Connect the penny to the red lead of the voltmeter using one of the alligator clips. Most voltmeters have red and black leads, but if your voltmeter has yellow and black leads, connect the penny to the yellow lead.

Connect the galvanized nail to the black lead of the voltmeter, and make sure both alligator clips are securely attached. Your voltmeter should show a positive reading. If it shows a negative value, simply switch the leads. You've produced electricity from a potato!

Construct a Balloon Hovercraft

You can make a small hovercraft that can slide along floors and tables by putting friction and Newton's Third Law of Motion into action. You'll need a balloon, the cap from a one or two-liter plastic soda bottle, a CD or DVD that you no longer use, an etching knife or scissors, and a glue gun.

First, create a nozzle by using the etching knife or scissors to create a hole in the bottle cap about the width of a drinking straw. Place glue all around the rim of the bottle cap, and attach it to the center of the CD or DVD. Wait for the glue to dry then check to see if has made a good seal with the CD or DVD, reapply glue if needed.

Blow up the balloon and pinch off the opening with your fingers then wrap the opening of the balloon around the nozzle of your hovercraft. Place the hovercraft on a flat surface and watch it go!

The Egg in a Bottle

This "oldie but goodie" experiment shows the relationship between atmospheric pressure and temperature. You'll need a couple of boiled and peeled eggs and a glass bottle or jar that has an opening that is somewhat smaller than the diameter of the boiled eggs. You'll also need a small piece of paper and a source of fire, such as a match or lighter. Parents should help kids with this one.

Place the glass container on a table and fold the paper into a strip that will fit inside the glass container. Light one end of the paper strip and drop the burning paper into the container. Next, set the egg on top of the opening of the glass container, and wait. 

As if by magic, the egg will be sucked slowly into the bottle. This happens because the burning paper has changed the air pressure within the bottle. Soon after the egg is placed on top of the container, the fire will be extinguished, and the air inside the container will start to cool and contract. This lowers the air pressure within the container, so that the pressure in the container is lower than the air pressure outside the container. Because a ir flows from a high-pressure system to a low-pressure system, t he higher outside pressure pushes the  egg  into the  bottle.

You can do all these experiments at home with kids, and they are a wonderful introduction into the worlds of science and engineering.

8 Awesomely Simple Science Experiments You Can Do at Home

Science can be a little intimidating. Whether it's the latest research in quantum mechanics or organic chemistry, sometimes science can make your head spin.

But you don't have to go through eight years of school or work in a high-tech lab to do science.

There are plenty of experiments you can do at home. You might even have a few of the materials just lying around the house.

Here are a few easy ways for you to see science in action.

Tornado in a bottle

You can create your own tornado in a bottle. All you need is two bottles, a tube to connect the bottles, and some water.

When you whirl the liquid in the top bottle, it creates a vortex as it drains into the bottom bottle. That's because as the water flows down, air must flow up, creating a spiraling tornado.

You can even add glitter, food dye, or lamp oil to the bottle to make the tornado even cooler.

Rainbow in a glass

This experiment takes advantage of density to create a rainbow in a glass. When you add sugar to a liquid, it causes the solution to become more dense. The more sugar you add, the more dense the solution is.

If you have four different solutions that are all different colours and densities, the colours will layer on top of each other — the denser, more sugary solutions will sit on the bottom and the lightest will sit on the top.

Gooey slime

When you mix glue, water, and a little bit of food colouring, then add some borax, a gooey slime forms. That's because the glue has something called polyvinyl acetate in it, which is a liquid polymer.

The borax links the polyvinyl acetate molecules to each other, creating one large, flexible polymer: slime.

Pasta rocket

Believe it or not, you can create a very simple hybrid rocket engine using nothing but some yeast, hydrogen peroxide, a jar, fire and … a piece of uncooked pasta.

When you mix the yeast and hydrogen peroxide together, they react and create pure oxygen gas. When this gas is funneled through a piece of pasta, all you need is a little bit of fire and you've got yourself a pasta rocket.

Homemade lava lamp

Alka-seltzer is great if you're suffering from heartburn or an upset stomach. But you probably didn't know that it's also great if you're looking to create your own homemade lava lamp.

Because oil and water have different densities and polarities, when you mix them together, the water sinks to the bottom. When you add food colouring, which is water based, it will sink to the bottom as well.

If you crumble in an alka-seltzer tablet, it reacts with the water, causing coloured droplets of water to rise to the top where they then pop, release air, and sink back to the bottom.

This creates a similar show to what you'd see in a lava lamp.

Instant ice

In order for water to become ice, it needs a nucleus in order for solid crystals to form. Usually, water is loaded with particles and impurities that enables ice to form. But purified water isn't. Because of this, purified water can reach an even colder temperature before becoming solid.

If you throw an unopened bottle of purified water into the freezer for a little less than three hours, the bottle will be chilled well below the temperature at which regular water freezes.

When you pour this super-cooled water onto a piece of ice, it provides the water with nuclei, causing it to freeze instantly.

Ferromagnetic fluid

This experiment makes it easy to see magnetic fields in action . All you need is some iron oxide, some water, and a jar.

When you place an extremely powerful magnet along the outside of the jar, the iron filings are attracted to it, piling up, and following the magnet as you move it around.

Baking soda volcano

In this experiment, a chemical reaction between baking soda and vinegar creates 'lava' bursting out of a model volcano.

As the reaction produces carbon dioxide gas, pressure builds up inside a plastic bottle hidden inside the volcano until the gas bubbles and erupts.

Fun With Physics! 10 DIY Physics Projects For Kids

Physics is fun. No, really, hear us out! We've put together a list of really cool projects to help your child gain a hands on understanding of physics fundamentals like inertia, momentum, pressure, and leverage. Witness the explosive effects of pressure by launching your own rocket. Build a pulley system using string and a broom. Watch confetti dance to invisible sound waves, and much more!

(Ages 8-16 )

Use the power of electromagnetism to create your own spinning sculpture! 

(Ages 9-11 )

Ever wondered if you can see sound? Well, in this experiment, you’ll use a Ziploc® brand sandwich bag to turn music into motion. It works because sound is a wave: a vibration that travels through the air (or another material) like a wave travels through water. Normally, we only hear these vibrations, and we can't see them. But by using the vibrations to make sprinkles dance, you’ll be able to see sound waves!

(Ages 9-16 )

How to Make a Pendulum Wave Toy

A pendulum is a hanging weight that swings back and forth, like the swinging arm on a grandfather clock or a swing on a playground. When you pull a swing - or any pendulum - up to one side, gravity tugs it back down. But since the swing is attached by a rope or chain, it doesn’t just drop to the ground. Instead, it swings back and forth, over and over.

But what happens when you have a bunch of different-sized pendulums swinging together? Make this mesmerizing pendulum wave toy to find out!

physics experiments diy

Water squirters work by pressurizing reservoirs of water with air. As you pump the squirter, it gradually adds air to the reservoir, increasing the pressure. When you pull the trigger, the pressure is allowed to release and a stream of water shoots out!

In this DIY project, we'll learn how to use the exact sample principles found in water squirters to launch a water rocket sky-high! Follow along with these simple steps and you'll be blasting off in no time.

Want to make a bottle rocket without the hassle of gathering materials? Blast off with a Bottle Rocket crate from the KiwiCo Store ! It includes a step-by-step video tutorial link, illustrated blueprint instructions, all the materials, and a special-edition Tinker Zine magazine for more project fun!

This setup is a compound pulley, which combine both fixed and moveable pulleys to increase the mechanical advantage.

In a pulley system, a wheel's job is to let the rope move freely. Here, this set up works with no wheels. The broom can act as the wheel since it's low-friction enough that the rope can easily move over it.
