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.


Particularly on topic for me because I have an Air Horn on my bicycle:

It uses what appears to be a slightly thicker version of a soda
bottle. It is a very effective horn, in fact, a bit too loud.

RTFM - it has a volume control.

That's no volume control - it's an on/off switch. They can say
whatever they want but I own one. Any touch strong enough to release
the air causes enough noise to make someone jump.
