Mad Scientist Costume

I made this costume for my grand daughter Leah. I bought the light up wig on clearance last year. The lab coat was a toy coat that I glued pockets on. I bought iron on patched.I made a badge with her picture on it. What made this a unique costume was the mad scientist lab that I made on a backpack.I put Styrofoam with lots of working lights.It had light up test tubes with glow Sticks a light up Petrie dish a skull with light up eyes and the bottom of backpack was a mad scientist chalkboard with scientific equations written on it.This was made out of chalkboard paper glued on bottom. She was a hit every where we went.
