Okay, so you know how sometimes grown-ups make art out of things that aren't usually used for art, like junk or garbage? Well, plop art is kind of like that, but instead of using junk, artists use things like foam or rubber to make big, bouncy sculptures that look like they just plopped down out of nowhere.
Now, these sculptures can look pretty cool and colorful, and they're fun to touch and jump on, but they don't have a lot of deep meaning or message like some other kinds of art. Plop art is just meant to be enjoyed and make people smile!
