Do you know somebody whose life mission during the holidays is to figure out what's in their gift box? Well, thanks to Instructables user DIYHacksAndHowTos, you can make sure your gift remains a surprise until the very last minute.
This prank requires just a little bit of tech know-how and some inexpensive parts to create a gift box that generates random sounds when shaken. The best part of this build is that it works with any present. Just put your gift into a box that's larger than the electronics and you'll be able to stump just about anybody.
Since you record the sounds yourself, you can choose anything from personalized messages or Holiday music to barn yard noises. Finish off your DIYHacksAndHowTos gift box with your favorite wrapping paper and you've combined the magic of Christmas and April Fool's all in one.
