For all of you DIY inventors, its time for the 2007 Rube Goldber challenge:

"Take a whole orange, juice it, and pour the juice from a pitcher into a cup - in 20 steps or more."

Schools like Purdue are taking part in this years contest. Rube Goldberg being famous for his cartoons depicting absurd and convoluted ways of achieving simple results.

Milk man takes empty milk bottle (A), pulling string (B), which causes sword (C), to sever cord (D) and allow guillotine blade (E) to drop and cut rope (F) which releases battering ram (G). Ram bumps against open door (H) causing it to close. Grass sickle (I) cuts a slice off end of orange (J) at the same time spike (K) stabs "prune hawk" (L). He opens his mouth to yell in agony, thereby releasing prune and allowing divers boot (M) to drop and step on sleeping octopus (N). Octopus awakens in a rage and seeing orange attacks it and crushes it with tentacles, thereby causing all the juice in the orange to run into glass(O).

Later on you can use the log to build a log cabin whre you can raise your son to be president like Abraham Lincoln.
