snowpocalypseWell for starters you need to mix boiling water so unless you can stand the heat might not work. Then you would need to get it cold for a very long time.... Also not easy. Lets say you fallow the Jigglers recipe for harder jello. First you would need all boiling water. Mix till its resolved then on ice for at least 10 hrs. Not too sure how you could do this but hell I'm down. Lets give it a shot.
You wouldn’t have to be in the water/jello mix while it boils, you just need to be in when it starts to cool/bond. But as you said, placing a tub full of jello in a cold enough place is the challenge.
I guess you’ll have to put a tub full of boiling water in a walk in refrigerator, mix in the jello, put on your ski gear (it’s cold in the walk in), then hop in the jello and wait.
We could probably get Jell-O to sponsor this, and maybe we can get some outerwear brand to sponsor as well go keep you warm in the walk in?
