Model hovercraft from an old CD

 A pretty handicraft project for kids on a Sunday afternoon!
 

	The basic construction: a PET bottle cap is glued to an old CD. The threaded part of a PET bottle is cut off, a balloon is pulled over the bottleneck. The rim of the cap can be trimmed a little to make room for the balloon's lip. A hole of 4 ... 4,5 mm is drilled into the center of the cap.
	Filling the balloon is easy: inflate it through the bottleneck, 1 turn of the neck closes the tubular end. Then screw the bottleneck into the cap. This arrangement had one disadvantage: while hovering over the floor, the balloon bent sideways, acting like a brake on the floor.
	To prevent the balloon from bending sideways, we made a paper sleeve.
	Tim, showing another filling technique.
	The finished hovercraft, gliding elegantly and frictionless over the floor. Nieces Hanna and Flora drive it through the room. Sorry, no sound available!
