This item makes a captivating demonstration for all ages! The Pendulum Wave Demo simulates phases, beats, and frequencies. It features a stand with nine (9) 0.88″ (22 mm) steel ball pendulums and comes with an initiator stick, which helps to simultaneously release all pendulums. When released, the pendulums will swing back and forth to quickly form a wave pattern and then cycle through different phases. This product is great for a classroom, as a gift, or for display.
• Comes with a Teacher’s Guide
• Flat packaging
• Comes unassembled. Easy assembly in minutes

This LED Array is a clever way to demonstrate color diffraction and the effects of colors on wavelengths. The Array is a fun and attractive way to show students the diffraction patterns of colors through use of 11 vertically mounted LED lights in different colors (violet, deep blue, blue, turquoise, bright green, green, yellow, orange, red, deep red, and white) that can be switched on individually or all at once by turning a rotary switch on top of the LED array.
• Each color bulb has the color’s name and its wavelength printed on the 12″ metal tube
• On/off switch on the back
• Uses a 110 V adapter
