The Holy Cow Greeting Card Bomb is a very easy and fun practical joke you can play on anyone of any age. It will take you all of 5 minutes to make, load, prime and deploy. You can even send it safely through the mail without fear of it going off on anyone other than the intended recipient (hereafter known as "victim")
It works by making a sudden loud racket inside an innocent-looking greeting card ("bait") as soon as it's opened. Scares the bejeezers out of the victim, and gives everyone else a good ol' giggle.
Using a rubber band, a small paperclip is wound up on the band which is stretched across a wire frame you make for the device (you'll see all that in the next steps). The Holy Cow Greeting Card Bomb is primed and placed carefully inside the greeting card bait which is then placed in it's envelope. The bait card/envelope can be sealed and mailed to the victim, or just handed to them as is..
The closed flat card prevents the paperclip from unwinding on the rubber band. As soon as the victim opens the card the paperclip spins and clatters against the card, causing a quite a stir and startling the victim. The victim quickly recovers from the ordeal and is instantly impressed by your clever device and fine craftmanship.
