There are so many different ways to use the loud shrieking Panic Button for your own amusement that it's hard to pick just one.
The Panic Button from Archie McPhee is a simple little device that, with a push of a button, will release an obscenely loud scream. Think of all the hilarious pranks you can pull on people with this little item. Want to divert attention for a quick getaway? This will be perfect for that. How about to scare the crap out of someone? Just push the button and I'm sure it'll startle someone immediately. Of course, as the site suggests, you can always use this as a way of expressing the inner rage from within if you just can't bring yourself to do it.
