Balloons
A great Science Project Invention of Flight Balloon
The hot air balloon Montgolfer flew over the French countryside in 1783, carrying aloft two men - the first humans to ever fly. This kit was Developed in connection with scientists, curators, and educators from the Smithsonian Institute, where a replica is on display.  This is one of the most fun kits we've ever offered.  The balloon is huge and it really flies. Making it takes only a couple of hours, and the end result is a five foot tall aerstatat that will soar far overhead on a cool day.  A couple of family hair dryers or a popcorn popper provide the heat need for lift off.  Caution: Your model Montgolfer can stay up a very long time and the wind can carry it some distance, so fly it where you can see for a long distance.  We also recommend the Estes Model Rocket Locator to aid in recovery.  CURRENTLY UNAVAILABLE.
