PSI limit for a hollow pumpkin

So... I am thinking next year for October I am going to do a pumpkin beer as a real ale served out of a pumpkin. My only concern is how much pressure a hollowed out pumpkin can hold before it explodes. I do like to plan ahead. Does anyone have any data on this? Perhaps I need to do an experiment this fall?

The PSI rating of a pumpkin is directly proportional to the wall thickness and inversely proportional to the size of the pumpkin.

I think some empirical data is required to develop the exact relationship.

Please post videos of your tests.

Didn't BYO do this at some point? Or maybe Zymurgy. I'm having trouble finding the article.

But whatever you end up doing, please do it on film

Strength of the pumpkin, besides the measure of wall thickness, is also a function of the moisture regime during the pumpkins growth.

I would keep the PSI low for serving, if I would try to do this.

Are you planning on naturally carbing it inside the pumpkin or transfering into it?

Since this is for a real ale (and I am assuming you have a hand pump) could you not carb in the keg and then decant into the pumpkin and hookup the hand pump with no extra gas... just like the real thing... although in a pumpkin

Better use a spunding valve

How does one hollow out a pumpkin and then repair it back into a pressure vessel?
