When Pamelia and I were at the Science Museum in London last fall, we watched a short film called On the Move. Drawing on the inspiration of crazy-invention cartoonist Rube Goldberg, it demonstrated energy transfer through a comical series of linked contraptions, burning fuses, rolling balls, falling boxes and other objects put into motion. The chain of events that unfolds on screen wasn't pieced together by a film editor; it actually took place, just once, after carefully being set up in a warehouse in Cornwall, on England's southwest coast.
Have fun watching the short version above, or click on the link below for the full version.
Fear not: As the creative geniuses behind the video inform viewers, "No toys were injured in the making of this film."
Answers to the Last Puzzlers
1) The question was posed this way: I’m looking at my watch. From this moment on, the hour hand will take exactly as long as the minute hand to reach the number six. What time is it?
