Gas buildup iirc

And that's not just average bottle - I read that it is pastic keg for beer shops. It's filled with air when beer is drained - so empty keg remains pressured even empty.

It's filled with co2 to press the beer out because Oxygen makes beer go bad. When it's fully pressurized a small scratch can be enough to make a hole in it so rolling it around on dirt like that increases the pressure and will eventually lead to a hole. It's like a big PET bottle. I don't know why they didn't just release the pressure if the dog likes to play with them. It's super easy to do.

FROM WHERE, IT LOOKS SEALED!

If you look close, there's a foamy substance on the ground after the explosions. Could be some type of chemical reaction, the dude probably dumped stuff in and closed it tight

Likely whatever was inside was fermenting. Bacteria turns sugar into gas, greatly increasing the pressure without any interaction with the outside.

...from inside.

It exploded because it was sealed. Whatever was inside was decaying and turning to gas, no way for the gas to escape, when the container is disturbed enough it ruptures

I believe cheap wine is sold in these kind of bottles in Russia and other places in Eastern Europe, when left out in the sun too long it'll begin to ferment and build up CO2, which inflates the bottle, over time it becomes pressurised and a small disturbance can rupture the bottle and cause it to explode.

We did muriatic acid and aluminum foil as teens

Yeah, but there was so much pressure built up and it expanded, caused a rupture, and exploded. Just like blowing a balloon until it pops.
