If you or your kids love slime, you'll want to check out this edible unicorn slime.
Made by Jell-O, the edible gelatin strawberry-flavored slime mix would make a fun play and snack time activity. It's pretty high in calories (290 for one serving, and there are 5 servings per package), but this could be a fun sleepover activity if you have multiple kids over to break up the slime.
Walmart and other retailers sell the edible slime online. Get it here.
