How long will the bulb last on a cup?

@egeqb18 The light bulb is plugged in to an outlet. The two prongs make it so that it is an open circuit. Putting the prongs into the minerals closes the circuit so that electricity can pass to the light. Essentially, the video demonstrates the amount of liquid minerals in each solution.
