The Unpoppable Balloon
Source Institutions
In this activity, learners explore polymer structure and their ability to reform around objects by attempting to stab a wooden skewer through a balloon without popping it.

Rocket Pinwheel
Source Institutions
In this activity, learners use simple materials to construct a balloon-powered pinwheel. The pinwheel is a great way to investigate Newton's Third Law of Motion.

Light as Air
Source Institutions
In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

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