Here's an easy and cheap prank for April fools day, or any day!
Almost any bin can be hacked to scream when opened using just some easily modifyable electronics and a limit switch.
This prank had to happen to have a use for the noise maker from a flying/screaming ThinkGeek monkey bought by Mikeasaurus. After flying around the Instructables office, spilling coffee and making far too much noise, threats were made on its life and so it had to be silenced.
Step 1: Tools & Materials
a glue gun
a screaming/yelling toy
