From The Physics of Fun

One part of physics that affects everything you do is friction! Friction is a force that occurs when two surfaces rub against each other. Smoother surfaces generate less friction, while rough or bumpy surfaces generate more friction. Check it out!

Most older roller coasters are pulled up that first hill. However, some newer coasters have pneumatic launch systems. That means a shot of compressed air launches the coaster up the hill. We’re going to build a simple version of that with a straw that you blow through.

Samuel L. Nerenberg, Doctoral Candidate of Optical Sciences
"An excellent introductory text for children to the field of optics. It provides a balance between scientific concept and history presented at an appropriate level. In addition, the included experiments are cleverly constructed and with a little extra investigation demonstrate some very fundamental aspects of the nature of light."
