EL wire is amazing, and the “chasing” el wire is even cooler. However, if you want it in several places on the costume, you end up having to figure out how to hide multiple inverters (or buy a more expensive uniit that has multiple taps). The Egg Sisters come to the rescue to show you that, while it can be a bit tricky, you can splice this stuff together to run multiple strands off of a single inverter. This also makes controlling the speed of the “chase” much easier.
