My son chose a really cool project for his 6th grade science project. We are observing and recording bats feeding at our pond, then he's going to make some sort of brilliant scientific deductions and I can retire early. Or at least he's going to put do one of those poster thingies for open house.

Anyway, he wants to put a push-button sound playback device on the poster. "Press the red button to hear a bat's call." He'll have to explain how the bat detector converts the ultrasonic emissions to audible sounds, but that's not my problem.

Anyone know of a push-button sound playback thingy? Red button preferred.

At least I don't have to help him build a mission again (4th grade project in CA schools. I will pay my 3rd grader to write a paper instead).
