These 4 easy DIY slime recipes are going to keep your kids so entertained this summer

Let's be real, kids love slime. It's pretty much an accepted fact of life at this point — and, if we're really being honest, Nickelodeon even had us in on the slime love back in our day, too.

Although slime is pretty disgusting, it is also an excellent way to spark imagination — and a little imagination is definitely needed during the long, lazy days of summer. Sure, you can buy a tiny canister of slime at the toy store, but it's super-easy, a lot cheaper, and so much more fun to make it at home. Just set up shop in the backyard (or put down a tarp inside), gather a few ingredients, and get ready to get slimed!
