How deep to crush a regular pumpkin?

[SneakSnake]

So it's that time of year, underwater pumpkin carving time. I have a question for those that have come before me:
How deep can you take an average carving pumpkin before it implodes? I think it would make for an interesting video to explain the physics of depth and diving, but I don't want to lug a giant pumpkin around on a dive if it's not going to crush. Any insight would be welcome. I wouldn't think it would be too too deep, less than 100'?

Extra points if you have a definitive answer

I found lots of videos of exploding pumpkins, but none of pumpkins imploding under water.

So it's probably deeper than I'd ever go.

Hi @SneakSnake

I think pumpkins are mostly like a liquid inside (seeds and gush), not sure it would readily implode at depth. That's physics and diving too.

Implode would require a void (air space) inside the pumpkin. Been a long time since I was in a pumpkin but I recall them being pretty full inside. Add in a tough shell in roughly spherical shape. I doubt you would ever get an implosion. Maybe at very deep depths you might get the top or bottom to deform a bit and maybe even crack equalizing pressures.

Have you cut open a pumpkin or squash? They are not liquid inside but contain fibrous, slimy strands and seeds.

That said, being more or less spherical in shape they would need to go pretty deep before they would implode. The best way to demonstration the effect of water pressure is a ballon.

I have taken a pumpkin to 100 FFW. It didn't implode, it just cracked and filled.
YMMV.

I doubt they would implode, the shell has a lot of air space in it and would compress and get soft.

More like a bag of pumpkin guts than implode

My guess is that at a relatively shallow depth that pressurized water would find it's way into the cavity and equalize far sooner than an implosion. But that's just a guess!!!

It took 14 pounds to get this pumpkin underwater. A group of us carved under water and pumpkins just get soggy. The fish weren’t interested in sampling the pumpkin guts.

Watch this hippopotamus crush a pumpkin:
According to the first thing I found on Google, a hippo's jaws bite at a pressure of about 1820 psi, or 125 bar: Who Has the Strongest Jaws in the Animal Kingdom? With Your Portland, OR Family & General Dentist.

So, as an upper bound, I'd say you're looking at no deeper than 4,125 feet / 1,250 meters. Hope this helps, good luck.
