Boiling pressure resistant bottles in a bath of oil, cheap PC?

WARNING this is an extremely dangerous proposal DO NOT ATTEMPT
Most beer bottles can handle high pressures. What if you were to load your grains in bottles with the correct water content. Then cap them and boil them in a bath of vegetable oil, heated to 121C so the pressure in the bottle would eventually be 15psi. Plastic PET soda bottles can handle huge pressure, I used to brew beer and we would make some rock hard, the foam would shoot up higher than a 2 storey house when opened.
Capping machines can be bought in brew stores, there are also cheap plastic press on safety caps which will blow off when a certain pressure is reached, well before the glass is likely to break. The safety caps have an indent which pops up when pressurized. I do not think these caps will work though since when heated they will soften and blow off far sooner.
This link has claims of 1 pint beer bottles going to 50psi. Champagne bottles to 90psi and PET over 100psi. PET is useless as it shrinks and deforms when heated. http://www.yobrew.co.uk/beer.htm
A metal safety valve could be attached to a jar and microwaved to vent at 15psi, you then turn the power down so it is barely venting (don't bother warning me about metal in microwaves, I know the truth)

How would you inoculate the pressure filled bottles? You'd need some sort of hole or filter to be able to get in, or when you popped the top open youd suck in a bunch of air and shit. I mean do you want the foam shooting up higher than a 2 storey building when your trying to inoculate it.

The pressure will be the same in the bottle after cooling. You will need air exchange though. You could inject through a cork. I have successfully swaped jar lids for filter discs after steaming jars. I boiled the disc and soaked it in alcohol. Then I unscrewed the lid, held it up and put the disc in underneath. All while the jar was still hot.
Otherwise you would have to empty the bottles into jars and steam them for a while, best done while hot.
Unless somebody can comeup with a better idea?

Hot oil and bottles under pressure...I say: get the emergency number ready before you are attempting it, you are going to need it, badly.

Yep you are probably right, I edited the post and stuck a warning in it. I am just really interested in the theory of it.

It is very easy to do. Get some bread yeast or the yeast from a bottle of bottle conditioned beer (cloudy beer with yeast in it). Then add a few spoons of sugar to some hot water in a 2 litre PET bottle, leave in a warm place for a week or 2 and it will get ROCK hard, all the dimples will blow out at the bottom where it usually stands up. I remember a friends found a bottle with only a few drops in it a few months after drinking it. It was a dilutable orange bottle so the cap was not designed for pressure release ( thats what the slits are in the threads of coke bottles). He opened the bottle and it ricochetted around the room and smacked another guy in the head.
