In this fast-paced, "need it done yesterday" world, who has the time to make individual house calls around the world to exchange cash for bloody molars? Recognizing the physical and logistical burden of the tooth fairy, this industrious dad built a tooth delivery system using a set of PVC pipes, a vacuum and a tiny computer. The pneumatic system is triggered via smartphone while the family is gathered at one of two delivery stations. Meanwhile, the "tooth fairy's helper" retrieves the tooth at the other station and sends back a container filled with cash. In the end, the kids are happy, the tooth fairy gets a much-needed break, and parents don't have to tiptoe around in socked feet at 2 a.m.
