You choose the cellophane bag which can be tied with curling ribbon and optional sweets. We'll fill it with 2 mini star glider kits; a giant paratrooper (with a parachute attached to his back, he can be dropped from a height and float gracefully to the ground) and a Chinese finger trap (get your victim to insert a finger into each end of the tube. They will struggle and pull to get their fingers out, but all this does is make the weave grip their fingers tighter! When you feel the torture has gone on long enough, gently push the trap at both ends to make it shorter and fatter again!)
