I've seen these things on the campuses for a while. Most of this school year, in fact. It's a snack size plastic bag full of red goo. And the students eat this stuff.
I clamp down on them when I see them. Because it's food and they're not supposed to be eating in class. And, it's a big, gooey mess.
(Students eating in class is generally a bad idea, because they tend to leave their trash everywhere. Add in sticky red goo...)
So, of course, naturally, some boy managed to get a big red blob on a desk. I made him clean it up, which was difficult as there were no paper towels in the room. Luckily, it was passing period. (This was the only reason he had the mess out in the first place.)
As I had a captive audience (as he took out a sheet of notebook paper to sub in for a paper towel), I finally had a chance to ask my burning question: What the heck is that stuff?
It's gummy worms in a slightly moistened Kool-Aid mix.
I looked it up. Apparently, it's a thing. You can find the recipe online...
So, um, yeah. If you're into that sort of thing, try it out. Although, I wouldn't recommend it. Not unless you don't mind red sticky fingers and goo that gets everywhere.
