The aptly named Princess and the Pea Alarm Clock will inflate you right out of bed in the morning. This homemade alarm clock consists of a powerful air compressor hooked up to a big exercise ball that goes under your mattress. When it’s time to rise and shine, the ball starts to inflate, pushing the mattress up and you right off the bed. Just make sure you don’t leave anything sharp on the floor next to your bed! Here’s a different video than the one above- showing someone actually in the bed getting ejected.
