Can dry ice hurt you?

Do you leave dry ice in the bag?

What happens if you pour water on dry ice?

If you mix dry ice with water, it will sublime—that is, change from a solid to a gas without existing in a liquid phase in between. If sublimation happens within an enclosed container, the carbon dioxide that’s produced will build up and this pressure will eventually cause a small explosion.

What happens if you put dry ice in the freezer?

If you keep it in the freezer, it will not only melt into a gas quickly, since the freezer is so much warmer than the temperature of dry ice, but it could also cause the freezer to shut down.
