There must be fourteen segments like this, each one eighteen feet long and two feet wide at the widest part, then tapering to a point at one end, the top, and to a width of five inches at the other end, the mouth, which must be left open. These segments are made from ordinary sheets of tissue paper, first pasted into long sheets (use ordinary starch paste) and then cut out after the pattern. Then the fourteen segments must be pasted together lengthwise along the edges, and they will form a balloon with enough lifting power to take up a parachute and small passenger, say a kitten or a puppy.
