Summary: Since I was a little kid I always wondered what it would be like to swim in a pool of Jello. Turns out it is really difficult. We heated up the Gelatin in 55 gallon drums and then used gravity to put that jello into the pool.

They are soft-

I make videos like this once a month all year long while supplies last:

  • That kid with the Peyton Manning Broncos Jersey was the best one there

  • Yo I like it

  • This is the first video i ever watched when it came out

  • Haha! The Jurassic Park scene was really funny. lol

  • If you use agar agar, which is a vegetarian substitute for gelatin, then you don’t need to refrigerate it.

  • 6:38 The song predicted Corona virus- the song litterally said corona virus if you listen closely

  • Your so creative some day I'll do that. Some how
