Last summer, YouTuber (and former NASA engineer) Mark Rober built the world’s largest NERF gun and terrorized his kids with it. This summer, Rober is getting into water sports, putting his specific brand of engineering to use building himself a custom Super Soaker. Where the original is hand pumped, Rober’s uses nitrogen tanks to propel jets of water, though Rober’s is still just a scaled up version of the original. Gas is still used to pressurized a tank of water and fire a stream at an unfortunate target. He provides plans for building your own, if you’re so inclined, but before you get to work, know a few things about the process. Rober’s a highly trained engineer who knows exactly what he’s doing, so if you are going to build this, find someone with the required engineering experience. Also, the water comes out at 272 miles per hour, so don’t let anyone stand too close to the nozzle. They might lose something important.

1-12-Scale-Pallet-of-Mini-Cinder-Blocks-IF2

[Shop]  We might not all agree on watches, wallets or other pieces of the everyday carry, but the one thing we can all agree on is our mutual love of building things out of small bricks. Forget plastic building bricks that can only be used with specific mats and upgrade your conference call and boring meeting building with this 1:12 scale mini cinder block pallet set. With 24 miniature cinder blocks and one pallet per set, this has everything you need to build a great foundation for the big box creation of your dreams. Whether you’re making a small creation of your own devising with the 24 pieces that come with it, or adding multiples to build something more grandiose, this is the best way to build when you’re not using plastic.
