Floating two objects in an airstream... the Coanda Effect // Homemade Science with Bruce Yeany

After posting a few videos on floating objects in an airstream, I received a challenge from a high school physics class wondering if it was possible to float two objects in the same airstream at once. Using the same parameters thet I used for other levitating objects, I was able to discover several pairs of objects that were able to levitate together. A large problem I ran into is the amount of air required for two objects tended to be a bit more than my air compressors could handle. In some cases the reduction in air flow as the tank pressure dropped was enough to limit the flight time.
