Hard Boiled Eggs
Electrical or Duct tape
2 next use the tape to put a design on the egg. I did duct tape the first time but electrical tape was much easier to maneuver.
3 place the egg into the mug and wait anywhere from 30 seconds to several minutes depending on how dark you want the color to be.
4 take the egg out and wait a few minutes for it to dry. Then remove the tape and repeat steps 2 and 4 with different colors.
