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.

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

My bucket list is now one item shorter. This was a brutal amount of work but a worthy engineering challenge. MASSIVE thanks to my buddy Devin Super Tramp for filming this so don't get used to this high quality from me. He is a living legend.

Can you do fill your pool with corn starch and water pls
AnimeGirl 10907
Hey Mark! This is kind of a complicated question but it would make life so much easier for me. In a town of 100 people, what are the chances of you running into someone you know at a place like Wal-Mart? What about different social classes, like introvert or extrovert? What about a town of 1,000 people? 10,000?
