The people of Reddit are a curious bunch, so when they came across this advertisement for Jell-O, they had to find out if it was accurate. You know, for science.
So they turned to the most qualified team on the Internet, the Slow Mo Guys, who are always willing to create a big mess in slow motion just for fun. Sure enough, the result is pretty close - a bit more like a creative way to make Gummy Worms, but still impressive looking.
Of course, it wouldn't be a Slow Mo Guys video if they didn't find a way to get the Jell-O all over Dan's face while they were at it.
