What happens when you insert a coin into dry ice? It screeches! - TopicsExpress

What happens when you insert a coin into dry ice? It screeches! It also vibrates, almost like the coin is shivering. Check out the video below. ... but why does this happen? Carbon dioxide is typically known as a gas, though it exists as a solid when it reaches temperatures below −78.5 °C (−109.3 °F). This process is called deposition, and goes directly from gas to solid. When temperatures warm up, it sublimates and goes directly back into a gas. When the half dollar is pushed into the block, the warmth of the metal sublimates the dry ice and causes a change in pressure. As the gas pushes past the coin, the pressure causes that shriek. After some time, the coin forms a larger hole in the dry ice, producing larger air currents that push the coin around, causing it to vibrate and appear to be shivering. youtube/watch?v=piCJTRDvpNA#t=14
