Eugh I suck at refs. So basically, you have the triangle on a stand on wheels, hooked up to a car battery. The triangle itself is made of different alloys, so depending on where you hit it, it makes a different pop. You dont actually touch the clapper and the Triangle, or else they would fuse together due to the large amount of volts/amps. A mesh, non-conductive glove must be worn at all times to protect you from dieing when using it, and to protect you from the intense heat wave created. Cont.
