Care for a soft drink? Now, have you wondered how it was chilled? Dry ice is nothing but frozen carbon dioxide. It sublimates (turns to gas without first turning into a liquid) and that is why it’s called dry ice.
There is no harm in cooling a drink with dry ice as long as it is food grade. It will turn to gas and though a little may get dissolved in the drink it won’t poison you. Don’t we drink soda? Soda is nothing but water that has carbon dioxide dissolved in it.
However one should not try to hold dry ice in the hand for too long. It is very, very cold (-78.5 degrees C) and it can cause a burn. For the same reason, one should not eat or swallow pieces of dry ice.
