Electric Vehicle Charging Station Costume

My son is wearing an Electric Vehicle Charging Station. He came up with the idea while looking at an EV plugged in to one in Boston. We cut out 2 pieces of cardboard about 3 feet long and 2 feet wide. Next, we cut a 7x10 inch hole about 4 inches from top of one of the cardboard pieces. Took the piece we cut out, bent it and taped it behind the cut out, leaving space between cut out and back of board. Made a "Charge Your Ride" sign on white paper and taped it onto the box using clear mailing tape. Super glued LED lights onto the back piece of cardboard so they shined through the white "screen". Then we cut a second hole in the same cardboard piece about 4 inches from the bottom of the first one. This time we taped a funnel into that hole. We cut holes 1.5 inches from top on each side and threaded straps through tying them back onto themselves. For the electric cord we used a washer hose and attached it onto the other piece of cardboard using a beyblade launcher. Cut two slits in the back piece for the straps. Lastly we covered everything with aluminum foil and mailing tape.
