Answer by  Rahman (29)

Fill balloons with air, oxygen and helium and make it to fly. The balloon filled with air oxygen will be at lower level than the helium balloon. Helium can be used for blowing soap bubbles which will be bigger than normal bubbles blown with normal air. liquid helium can be used to demonstrate superconductivity.

You can prove that helium is lighter than air by filling up two balloons, one with air, and the other with helium.

I've had students fill balloons with helium with a small platform hanging from it with a toy person onboard. They try to knock off another student's person, without loosing their own. Balloons are attached to the student via a string. Needs to be done in a gym.
