There used to be a show called Street Cents on CBC that focused on consumer and media awareness. On one episode, they torture tested Nalgene bottles.
It's been a while but if I'm remembering right, I watched them survive:
- being thrown off a building
- being run over by a bulldozer
- being dipped in liquid nitrogen and hit with a hammer
- being heated with a blow torch
The lids broke in some of the tests, especially if they had liquid in them, but the bottles themselves are basically indestructible.
I've seen a knock-off bottle break when somebody set a backpack down on it too hard.
They send you an altered cashier's check (amount changed from $5 to $500 or whatever) and ask you to keep $400 and wire back $100. If the bank doesn't catch the fraud at the time you cash the check and you complete the transaction, now the scammer has your $100 and you are on the hook for the amount of the fraudulent check after it fails to clear.
