The English Scientist, Neil Downie, has written three volumes of Saturday Science Projects. His designs are remarkably original and thoughtful, explaining the math and science of every project.
Sometimes you have to strip away all the non-essential parts to see an idea at work. Neil Downie proposes a clever study of the exchange of speed for force. A second array of pulleys float between input pulleys and the output pulley. An elegant display of force in motion.

Counting on friends: what can your little acrobats tell you about the changes in speed or power (torque)?
