Plastic doesn't tear just because you feel it's weaker than it used to be.

Are you sure? I really believed that the plastic water bottle I stepped on yesterday immediately cracked and crushed directly as a result of my belief that the plastic is weaker. The power of the mind.

I guess it was just physics and material science.

And, You are being childish.

Thank you, that means a lot. I still feel young inside despite getting older, so that compliment means a lot.

For a moment of seriousness: people can step on and fall on any bottle, and no shit clubs are going to do everything to cover their ass (or at least be able to say they did in a court).

A full, unopened water bottle will definitely make you fall easier. But an empty bottle? No. It can still make you fall, but it's just as hazardous as an empty water bottle with no cap.

Again, unless we're talking about the couple major Coke and Pepsi brands that still use thick plastic.
