Anyone know at what PSI a typical plastic soda bottle explodes?

I've built a home carbonation system. The gauges say I've put in 150PSI of
C02 into the Trader Joe's (admittedly thick) carbonated water bottles.

Nothing happened (with respect to explosions).

Yet, as I dig on the web, I find that plastic soda bottles are supposed to
explode at 120 to 150psi.

Obviously I need more data.

Do you have data points showing when soda bottles explode?

PS: If there's a soda or carbon dioxide related newsgroup for home
carbonation, please let me know.

They do blow up and with considerable force. My neighbor's friend
works in the bottled gas business. His company makes dry ice. He gets
it for nothing and uses it for keeping his beer cold when he comes out
here for the weekend. He likes to make loud noises by dropping dry ice
into plastic pop bottles then sealing them up.

Better than the big firecrackers we called blockbusters when I was a kid.

You wouldn't want one of those bottles next to your crotch if it
decided to go boom.

SM, don't try to impress the kids at church. Someone will get hurt.
