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.

Grab it in a ton of fun colors, including burgundy, teal, pink, purple, and more.

This Squatty Potty That Isn’t Hideous

Let’s be honest: most toilet stools are ugly. Who likes having a giant piece of white plastic kicking around their bathroom? Not me, that’s for sure — which is why I have a classy squatty potty made from bamboo, like this one. There are rollers on the front where you can massage your feet, as well as a pocket on the side where you can stash your phone. As far as craptacular products go, this one is totally worth it.

Or, if frying isn’t your thing, you can also use it to make stir fry since it turns your regular pans into a wok. Grab it in three colors: red, orange, or black.
