If you have a notorious present shaker on your Christmas list, prank them with this meows-when-shaken present.

Who hasn’t jostled a box before opening it, attempting to surmise what’s inside? This entertaining prank plays off of that shake-the-present urge by turning a simple off-the-shelf audio module into a sound-producing trigger hidden inside the box. You can record whatever you want on the module but we think the guide author’s selection of a meowing kitten is a pretty clever choice. Watch the video above to see it in action.
