Pressure Bottle Rocket(Ages 9-16)
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!
Flying Teabag(Ages 7-16)
Make a tea bag fly with heat! The flying tea bag experiment is a similar concept to a hot air balloon, but you can do it right at home. This project is simple to create, but impressive to kids and adults alike!

Flaming Torch(Ages 9-16)
Create a whirling fire torch of your own. The flames spin upwards into a vortex from the rising heat and wind. Follow along to safely create a whirling fire torch yourself!
Electromagnet(Ages 9-16)
Unlike the magnets that are used on refrigerators, electromagnets are magnets that can be turned on and off depending on the flow of electricity. The electricity that flows through the wire allows the molecules in the nail to attract certain things. Give this experiment a try, and see how many paper clips you can pick up with your electromagnet!
Rubber Band Racer(Ages 5-16)
