# 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!

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

Explore more spintastic artistic wonders with a Spin Art Machine from the KiwiCo Store! Engineer a motorized spinning platform, then load your machine with paper and drip paint to make it splatter.

• Ever wondered if you can see sound? Well, in this experiment, you’ll turn music into motion.

Want to explore more kitchen science experiments? Explore the tastier side of learning with Science of Cooking: Ice Cream from the KiwiCo Store!

• ### 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!

Explore more methods for creating motion with the Hydraulic Claw Project from the KiwiCo Store! Engineer your own hydraulic lifting claw with tubes, syringes, and water before putting it through a series of fun challenges.

• 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!

• Cartesian Diver

(Ages 5-11)

Explore the science behind density and pressure with this DIY bottle diver!

Expand your oceanic adventure with ! This kit includes everything needed to create a color-changing reef, build ocean animals, and more!

• Take your paper airplanes to new heights by making a motorized launcher for them.

Build more awesome electronic vehicles, all from one convenient kit with a Make-It-Move Electronics Set from the KiwiCo Store!

• Are slinkies magical floating toys or do they somehow follow the laws of physics? Grab your favorite timeless fidget toy, head outside, and find out for yourself!

• Newton's Tower

(Ages 5-11)

Use excess office supplies to experiment with and learn about inertia!

• Compound Pulley

(Ages 9-16)

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.

• Learn about helicopters by making a rubber band powered flying toy!

Discover more about the physics of flight with a Bottle Rocket kit from the KiwiCo Store! Assemble a launcher, rocket, funnel, and launch mixture to experience some extremely fizzy fun.
