Find the vibrator

So, in science, I was explaining the difference between direct current and alternating current.

Me: Can someone give me an example of something that runs on alternating current.

Student 1: The computers.

Me: Right. What about direct current?

Student 2: The pencil sharpener.

Me: Try again.

Student 3: The television.

Me: Try again. Remember batteries provide direct current.

Student 4: A cell phone.

Me: Yes when it is not plugged in and charging up. Anything else?

Ismael: A vibrator.

Me: Correct. If it's battery operated. Anything else?

Student 1: A Gameboy.

Me: Yes. O.k. time to get ready for Social Studies.
