In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.

This activity is an investigation of static electricity. What happens when you get "static cling?" Basically, you pile up electrons on one thing, which attracts the protons in something else.

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

In this hands-on activity, learners explore static electricity through the use of common household products. They also explore the connection between static electricity and cold weather.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
