9 Volt Battery Noise Module PRANK

This is a 9 volt battery module that will make very annoying noises. Hide this small device anywhere and annoy the crap out of your friends. Let's get started :)

Take the top off a 9 volt battery with some pliers or anything you want to use.

Twist the wires onto the back of 9 volt battery clip you just made.

Tape the wires so they stay in place

Attach one wire from a color changing LED to one of the wires on the clip. Make sure it's the right wire or it won't work.

Attach the speaker to the two wires that you have left. Now the circuit is complete.

Tape the circuit down and make sure the wires don't touch.

I had to take off the top of the speaker because it wall blocking the sound.

It's so small so u can hide it anywhere.

Now that it's finished you can go and hide it. The newer the battery the higher the sound frequency.
