Instructables

Step 6: Finished!

Hooray! now we get to test it! If all went well (and my instructable was accurate), the siren and ping pong ball light should spring into action at the press of the button! As you can see from the picture, I made a crude button holder by poking a hole in the top of a disposable cup. I also cut a notch in the side to let the wires out.

Thanks! I let you in on a little secret: The ping pong ball wasn't my idea (I saw it online somewhere!)
