Fireworks Tour

Join our museum educators for a drop-in tour of our special exhibition on the fascinating history and science of pyrotechnics.

Thomas Paine and Joseph Priestley are seated at a table with guns, knives, a dish says phospherous, a gun butt says "Royal Electric fluid." A winged puti grins at them squatting in the center of the table. Books on treason, murders, assistination, revolution, etc. surround them. At Priestley's feat are packages of brimstone, axe and pickax. On the walls are scenes of execution and assassinations.
