The mystery of Benham's Disk
Turn a CD into an excellent spinning platform. Spin the CD with the Benham’s Disk pattern on top and explore the interesting effect that happens. The spinning black and white pattern creates an illusion of seeing colors in the spinning disk. It also reveals an interes..
What can keep a simple structure from collapsing during an earthquake?
How will an earthquake, simulated by shaking, affect a "building" made of linked squares? How can the square "stories" be cross-braced to prevent the "walls" from collapsing? What dangers are there in building above a garage?..

A clever way to demonstrate the transfer between potential energy and kinetic energy
Create a model car consisting of a simple chassis and a straw-based axle system (simple machine) that produces minimal friction and allows the cars to roll with little energy input, making them ideal learning too..
Discover the rainbow of colors in white light!
White light is actually a combination of different colors. This easy-to-build spectroscope allows students to separate the incoming light into its component colors, forming a light spectrum (rainbow). Besides creating interesting color patterns it c..
