Make sure to watch Junkyard Wars on TLC (and it’s kid version, Operation Junkyard on NBC Saturday Morning).
Teams are given 12 hours to build some crazy contraption out of stuff they find in the junkyard. The one I most recently saw had the teams building death traps… er… honest-to-God, working SUBMARINES that someone had to pilot the length of a very deep, very long industrial pool.
One team used an old propane tank (the kind you see a lot in rural areas), and the other team used an old VW Bug.
Whenever they show the teams welding stuff, I get all excited because I can appreciate what they are doing.
