Yes and the extremely thin plastic that the bottles are made of these days cracks and lets that air out as soon as force is applied.

Maybe you all drink Dasani exclusively or something, but most bottled water these days comes in plastic that's as thin as tissue paper. I have had that shit crack in my hands.

[I'm starting to enjoy the response I'm getting to this take. The passion, anger and vitriol directed at me for questioning this shit. It's hilarious, and I just can't help myself... Stepped on an empty water bottle with a cap on today and guess what happened? It was immediately crushed, and I am not a heavy person. Please, tell me again how angry that statement just made you]

I suppose... Have you felt how thin the plastic is on water bottles these days though? I feel like the plastic would give first whether there's a cap on or not. Maybe depends on the person's weight.

Edit: Lol lots of angry folks here. To the person who said I'm ignoring "actual data": what fucking data? Somebody said a thing, and now that's "data"? You've got some actual data about the dangers of stepping on water bottles?

It seems like people are referring to unopened bottles of water. Didn't see anything to indicate that in the original comment, but I guess it makes a little more sense if we're talking about unopened bottles of water. Since we're talking about trash that people throw on the ground, I guess I assumed the bottled was not only opened, but empty. Because it's trash.

That said, I stand by my original comment. Plastic water bottles are made of fucking tissue paper these days. They 100% would snap if someone stepped on an opened/empty bottle.
