Reducing friction by an air stream

Cut out a disc of cardboard about 10 cm in diameter. With a red-hot pin, burn a hole by the centre. Saw a small cotton reel in half and glue the unique end of one half over the middle of the disc. Search a piece of bamboo or some other tube which just fits the hole in the reel. Push this into the neck of a small balloon, using cotton or a rubber band to protected the joint.
