DRY ICE

Dry Ice is frozen carbon dioxide. It is so cold that at room temperature it will not "melt" but sublimate. This means it will change state from a solid to a gas skipping the liquid phase. There are many experiments and demonstrations that can be done with dry ice. In this video we highlight the frictionless nature of dry ice when placed on a table; the bubbles it makes when placed in water as well at the condensation cloud it forms; the cold high density nature of carbon dioxide gas and its ability to displace oxygen and thus can put out fire; the screaming spoon which vibrates as the heat of the spoon increases the rate of sublimation and the escaping CO2 makes a sound; the acidification of water as measured with a universal pH indicator solution; and finally the pressure that builds up as carbon dioxide is released from the dry ice and thus can provide for explosive consequences. Enjoy!
