Mad Scientist Frank N Stein Costume

My 3 year old Leah was a mad scientist with a lab on her back! Her backpack was turned into a walking lab equip with beakers of slime, petri dish of flies, rats, bugs, and a skull with red glowing eyes! Many lights throughout the backpack to light her up at night along with a pocket full of glowing spare body parts. Every nook has something in it that glows. We used an old backpack and put Styrofoam inside. We then covered it worth black mesh and pinned everything to it. Glow Sticks were used inside every beaker along with slime for that added touch.
