Light It Up

Eddy Current Tube Demo

This classic physics demonstration shows how a magnet falling through a copper pipe will slow down as it transfers some of its energy to move electrons in the conductive copper pipe. Those moving electrons create a magnetic field which interacts with the magnetic field of the magnet to slow it down. This document describes how…

Pepper’s Pyramid Projector

Pepper's Pyramid hack atop a cell phone screen

Turn your cell phone or tablet into a 3D hologram-like projector using plastic you would normally recycle. Reuse flat clear plastic to give this old physics trick a high tech twist. Less ecologically friendly, but good if you want to make a bunch of projectors, you can print templates onto transparencies and cut them out…
