Jeff Highsmith, a father of two, decided to re-write the Tooth Fairy experience for the 21st century. He built a pneumatic transport system that could send the teeth of his kids to the Tooth Fairy in return of some payment.
He set up the transport system by using 1.5″ PVC pipes with a central vacuum in the attic and two endpoint stations, one in each child’s room. When the child lost his tooth, he placed it in a small plastic bottle that traveled from one station to the next, while one of the parents put the money in another bottle at the other station to send back. 🙂
