Need help with an experiment involving jello

So my friends and I are all high right now and chatting and I thought of something weird that I'd like to find out.
If you jumped from 100 feet into a pool of jello, how deep would it need to be in order for you not to die/get hurt?
Or is jello so easily broken that the depth wouldn't matter? What's the tensile strength of jello?
My friend thinks "it wouldn't matter due to the sheer smack of hitting the jello's surface."

it would cut out your shape into the jello but i think that you would probably die no matter what

Wow, that is some stoner thinking right there. Pretty sure mythbusters covered that. You can probably find it somewhere on youtube.. Or just search up jello pool.

Back in Physics I, we calculated the depth of snow necessary to cushion a person's fall sufficiently so that they wouldn't die when falling from an airplane at terminal velocity. We assumed that the snow applied a constant decceleration to the body and used some published value for the maximum acceleration a person is able to withstand. It came out to only about 1 meter of thickness. You could do the same thing with jello and follow the same assumptions and the answer would come out the same. In your case though, terminal velocity probably isn't reached in 100 feet of free fall so the necessary thickness might be less.
In reality though, there are all kinds of things wrong with this model.
