    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:
