Solution is a pearly-white, water-based solution that can be used to demonstrate concepts that are usually difficult to see, such as ocean currents, turbulence, and convection. Adding food coloring makes it even easier and more exciting to simul..

Tank Features a 4-watt LED light that strobes at the same frequency as the agitator, allowing the two to be completely synchronized. This results in highly distinct and visible ripples that can be seen from a distance when projected onto a transluce..

This small, handheld unit features a large digital display and an analog bar graph for making high performance sound measurements. Calculate the range automatically or manually. Provides A or C frequency weighting and fast or slow time weighting. Also f..

The 4 ft. Slinky Spring with three times the normal length is ideal for demonstrating several fundamentals of wave motion. When the spring is extended to 30 feet, a lateral or longitudinal pulse can be observed in detail as it travels at the slower rate..

Longer and heavier, the spring demonstrates the effects of greater mass and of greater tension.
