Sand Blasters

So I watching this odd ass show on the travel chanel called Sandblasters that is a competitive sand sculpting contest where each sand sculture has an explosive under the pile of sand which periodically through the 2 days session they stop everyone and randomly blow one up. The sculptors then go back to work and the balasted one tries to recover and the unblasted ones hope the blast didn't fracture their work

There's no good web page for it (there's a lame one off the travel channel website)but I did find this page:
http://www.globalsand.com that's a community commited to sand scupture.
