Feet Leeches

The gift package is opened to reveal what appears to be a pair of rolled up socks. You try to hide your disappointment as one of the folded tubesocks is removed from the unwrapped clear plastic container as you are urged to try them on. On closer inspection these are not typical socks. They have a slippery texture and an unusually heavy weight. One end of the sock is tightly cinched closed and the other is wide open awaiting the insertion of wiggling toes.

Grasping one sock by the opening, you push your foot inside. As you do so the tight seal inside the sock is broken, and the negative pressure inside equalizes to the outside. The internal spring, no longer held compressed, inflates and elongates the tube as your foot is instantly gobbled up. You shriek in surprise as onlookers laugh as they indulge in the sight.
