For the past few years, Grant Thompson has spent his weekends starting fires, building cannons, and experimenting with dry ice and liquid nitrogen. He’s made pumpkins explode, defied gravity, and discovered countless ways to make everyday life easier using ordinary items such as butter, suntan lotion, cupcake wrappers, and aluminum foil. His discoveries and experiments, many posted online to sites such as YouTube, have earned him the title of the King of Random.

With the help of the staff at Instructables.com, Thompson has compiled the best of his weekend projects in Life Hacks. With life hacks from the King himself, you’ll see how easy it is to have better summers, less stressful holidays, and cooler—literally—birthday parties.
