I recently saw a video on making liquid $\ce{CO2}$: https://www.youtube.com/watch?v=8AN_XMcD3yI
Basically we seal some dry ice in a container. As the dry ice sublimates the pressure inside the container increases and so at about 5 atm we reach the triple point of $\ce{CO2}$, at which point the solid $\ce{CO2}$ melts instead of sublimating.
At some point in the video, the teacher cautions that the same experiment should not be done with a Gatorade bottle (similar to a water bottle). However, I'm not sure why this is the case.
Certainly the usual "dry ice bomb", which also has warm water poured into the sealed bottle, is not a good idea. In the present scenario, once all of the solid $\ce{CO2}$ had melted and the liquid $\ce{CO2}$ then goes into the gas phase, the increase in pressure could lead to an explosion: isn't this the same principle as in the case of the "dry ice bomb"? Is the warning because a Gatorade bottle (or water bottle, etc.) cannot withstand 5 atm of pressure?
