Junior scientist India show us how to build a rotocopter, a simple device that relies on the Coanda and Bernoulli effects to keep it 'stuck' in a pocket of fast-flowing air and helping it stay airborne. To create your own rotocopter, you'll need a balloon, a hairdryer, a plastic cup, string, electrical tape, scissors and a pen.
