School science teacher Bruce Yeany demonstrates his String Shooter, a simple machine that launches continuous loops of strings that hold themselves up and form interesting shapes in the air. Yeany shows how the loops behave when pushed or when the launch angle of the String Shooter is changed while explaining the physics at work.
The string shooter can launch a 8 foot loop of string that has some very interesting properties while it is in motion. The string is moving quickly enough be be self supporting and does not need to touch another surface for support.
