Due to required maintenance, a shuttle service will take visitors to our rear entrance on Gateway Blvd. For the OMNIMAX® Theatre, enter through the front entrance.
The ketchup is connecting the brass in the hook and the aluminum foil, acting as a conducting fluid that allows the hook to pull electrons (very tiny, electrically-charged bits of atoms from the aluminum).
The moving electrons are the electric current! It’s not a big enough current to light a light bulb (about ½ volt), but the loss of electrons is enough to change the composition of the aluminum so that weak acid vinegar) in the ketchup can start to dissolve it. Thatʼs where the holes come from.
