Last but not least: Birthday card from Hell

This is what the world was apparently waiting for: 7500 dollars Travis and Nick Peterson wanted on the portal Kickstarter.com for the development of the "Best Prank Birthday Card Ever!"; over 35'000 dollars have been raised to date. The highlight: once started, the annoying birthday song cannot be stopped. At least not without heavy artillery. Water, for example, won't harm it; the recipient will have to reach for a hammer or start a fire.

The idea may be simple, but the implementation is not. For example, the card has a security mode to write and test undisturbed. When the tab is removed, the card is armed - "like a Grenade!" in other words. Particularly beloved recipients can also be surprised with a volume mode: The music then gets one step louder with every attempt to turn it off again via the start button.
 

Those hoping for gracious assistance from the battery will likely be disappointed: it lasts a long time. This is proven by an almost five hours proof video.

One wonders what happened to all the good ideas when they were not yet funded and realized by the Internet. (hae)
