On April 12, 1985, NASA launched their Toys in Space program for school students.
Astronauts Rhea Seddon and Jeffery Hoffman used items like a Slinky, ball and jacks, Rat Stuff, gyroscope, and more to demonstrate how toys would react in space and the effects of weightlessness.
NASA included the toys of which I have most of them and a manual of preparing the class for the experiments done on land and then in on the Space Shuttle Mission STS-51D.
I have included a NASA video of 25 years in Space. This shows the 1st 7 astronauts, Mercury Flights, Gemini, Appollo Moon landings, Skylab missions, missions to Mars, Venus, Mercury, Jupiter, and Saturn, and NASA test programs, and much more. This is a spectacular video as only NASA can produce.
Included are the directions for folding a Steel Blade, Blue Bomber, and the Rose Sheet, Green Goblin, and the Invader paper airplanes. Using a paper clip or clips to show how the paper planes react. Students really enjoyed making and flying these airplanes!
