37 Shark Tank Inventions on Amazon That Are Pure Genius

There's nothing better than kicking back on the sofa and watching a 10-hour Shark Tank marathon in your underwear. Well, maybe a few things are better — eating burritos, finding $100 on the ground — but that's only two! Every other imaginable activity clearly pales in comparison. But if Shark Tank doesn't happen to be on, you can get the same level of entertainment by checking out all the genius products that've been featured on the show.

Bonus to keep one thing in mind while you're scrolling: think of all the independent entrepreneurs you're helping with your purchase and know that it's vetted by The Sharks themselves! Then add whatever it is you're looking at to your cart like I did, of course.
