Reflecting in the bath

An internally frosted, large light bulb is dipped into a fish tank of water, and the total internal reflection effect produces ‘other-worldly’ consequences to how the bulb looks in the water. The bulb goes from white to a silvery orb. Turning the bulb on, produces a similar, but more alluring effect. Parts Needed 1 Large, internally frosted light bulb 1 Light bulb socket, with cable and plug 1 Fish tank filled with water, Electrical tape
