Warning: Don't try this at home. Seriously, some of you have wild imaginations.
In case you've never heard of the Shamwow, go spend a few laughter-filled minutes on YouTube right now. For those of us who've seen the infomercials, here is the latest iteration in the form of a supposedly very strong steel tape that can seemingly do everything from fix broken tools to hold together a roll cage that encapsulates a car being thrown off a 140-foot vertical cliff. When this spokesman first tries the stunt, he's only using duct tape and as you can imagine, the car doesn't live to tell the tale.
After using his miracle product, the second car destined to be sacrificed amazingly holds up quite well.
