This EL wire (electroluminescent) hour glass is actually a fairly simple build. It’s built around a three foot long tube with two wooden rounds attached at either end. Then, a motor is added to one end to spin the EL wire around the tube to create the hour glass illusion.
Attaching EL wire (can be picked up fairly cheap on eBay) in five colors around the wood round and the pipe is the final finishing touch. The El wires are connected to a sequencer that triggers the five colors in a timed manner. Check out the full instructions to build ti yourself!
