Is it dangerous to put dry ice in water?

If you put dry ice in water, the carbon dioxide will turn to gas and then bubble out. The carbon dioxide gas itself is toxic if you breathe it in high concentrations () and of course it is also very cold. Dry ice should be handled with gloves or tongs so as not to cause frostbite.
