Make this continuously moving Hovercraft. You will need an old CD, glue, bottle cap and a 1-meter flexi plastic pipe. Make a hole in the bottle cap and press fit one end of the flexi pipe. Ensure there is no leakage from the joint. 
Apply rubber adhesive in the middle of an old CD. After the glue dries fix the lid on the centre of the CD. Wait for a while for the glue to dry.
This is the top view.
This is the bottom view. You can see the pipe is slightly inside. 
Now place the CD on a smooth surface and blow through the tube. The CD will float freely on the surface sometimes to the left, sometimes to the right just like a Hovercraft.
