You should hear the buzzer go off. If you can’t hear it, review steps 3 to 5 and make sure everything is correct.

Now dip the ends of the popsicle sticks in the salt water, make sure the ends are not touching each other. You should hear the buzzer go off, this is because the sodium and chlorine ions are carrying electricity as they float freely in the salt water.
