Measuring the Acceleration Due to Gravity with the g Ball
What is this about?
Galileo claimed that all objects fall toward Earth with the same acceleration. Modern measurements indicate that this acceleration is about 9.8m/s2. Using the G-Ball by Arbor Scientific, you can measure this value and compare the acceleration of other objects with different masses and in different states of motion.

The Blue-Violet Laser
The wavelength you've been missing!
Take a look at the new blue-violet Laser, which produces wavelengths at 405 nm. Sure, it is a different color and that is always cool, but why use this over any other Laser?
