I've heard that people use dry ice with drinks, but I'm wondering how safe that is. Since dry ice is carbon dioxide, isn't that dangerous?

  • Hi there, and welcome to health.SE! We like to have clearly asked questions here, maybe with a bit more information like background of the question too. For example, maybe you're preparing a punch bowl for a dinner, and want to add dry ice to it or perhaps you're just curious about swallowing a cube of dry ice (bad idea). I've edited it to say what I think you meant to ask. Feel free to roll back any changes or make some more. I'll try to answer this by today.

In addition to the extreme cold of dry ice when it warms and becomes a gas again it gains volume rapidly. If it is in your stomach you will inflate to fatal levels. There are many cases where this has happened. If you are drinking a beverage with dry ice in it make sure it has all evaporated (melted). It is used because of the 'cool' steam it gives of as it heats.
