At many amusement parks in the northeast (NH and MA) they have wax hand
booths where kids put their hands into large bats of wax, making layers and
layers of wax over their positioned hands. They finish with colored layers
so the hands can be three or four colors in layers or stripes. Then they
loosen the wax around the wrist and help kids wiggle out of them. This
could be done in a similar case with the wax therepy buckets they sell for
arthritis (at walmart, and other low-end stores).
