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 :)
Step 1: Take Off the Top
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.
Step 6: Now Tape It All Down
Tape the circuit down and make sure the wires don't touch.
Step 7: Take It Off
I had to take off the top of the speaker because it wall blocking the sound.
