Star Trek aficionados may recall the episode where Captain Kirk gets transported down to a planet by super-powerful aliens in order to do hand-to-hand combat against the Gorn. Without giving away the plot - in case you were deprived as a child and never saw the show - Kirk used his wits to defeat the lizard monster by assembling a primitive cannon from elements he found lying about.
Now comes Dylan Hacker - who I'm assuming goes by his "stage" name - runs a San Francisco production company called Household Hacker. This morning we stumbled across his highly entertaining video recipe for putting together a "Superman hand cannon" - basically an enhanced tennis launcher, assembled from bits and pieces of junk that probably are lying around your basement - and just in time for the summer. Definitely worth a look-see. (It's amazing how far duct tape will take you - especially on the odd chance that you, too, run into a Gorn somewhere down the road.)
