How to Sharpen a Pencil

Rube Goldberg Machine Contest

Looking for something to while away the hours during the long wait until the last Harry Potter book? Look no further!! The 20th National Rube Goldberg Machine Contest is happening in West Lafayette, Indiana, on March 31. As you can see from the above picture, Rube Goldberg delighted in coming up with very complex ways to perform very simple tasks. For those of you not familiar with his fabulous inventions, come to the library and have a gander at the book Rube Goldberg: Inventions, by Maynard Wolfe.

This year's challenge: Take a whole orange, juice it, and pour the juice from a pitcher into a cup in 20 steps or MORE. Remember, the deadline is March 31, so get juiced!
