How to Make a Musical Booby Trap

In this instructable, i will show you how to easily create a sound prank.

Cost:
Under $5.00

Tools:
*scissors

Materials:
*Musical greeting card (you can find it at CVS)
*String
*Tape

Make sure the card is a musical one (plays sound when you open it). Check for the white tab in the picture.

Take off the inside cover (Usually what is written on). What you see should look something like you see above:

Cut out the chip. Remove the white plastic tab, you  won't be needing that. Now cut out a small piece of paper and put that where the white tab was. The music/sound should stop playing.

Get a piece of string (it doesn't matter what kind, but thread works best). Tape that to the paper you put under the metal tab. That is your finished prank!

Tape the chip to a stationary surface. Tape/tie the string to the thing you want to trigger the noise. Make sure it is hidden. If it works, the object being picked up/moved will trigger the sound. This is great for things like doors, car keys, etc. Have fun pranking!
