The BCE (“Best Class EVER”) - Dry Ice Day
Yvonne Clifford | Mon, 12/19/2022 - 08:01
That it was the "Best Class EVER" seems to be the common refrain every year by most every one of Yvonne Clifford's students over the past 30 years after the Dry Ice Day. This is an engaging chemical to bring to the chemistry classroom or an outreach event because many concepts can be applied and it affords a great deal of fun and excitement!

What happens if you cool a Scrub Daddy sponge in liquid nitrogen (or dry ice) and subsequently strike it with a hammer? Let's find out!
Chemical Mystery #9: Liquid Nitrogen vs. Dry Ice
Tom Kuntzleman | Thu, 01/12/2017 - 07:20
A 2L soda pop bottle is filled about one-third full with either liquid nitrogen or solid carbon dioxide (dry ice) and water. The bottle is sealed and a plastic bucket is placed on top. Do you think the liquid nitrogen or dry ice and water will make the bucket go higher? Can you explain the results using chemistry?
The Dry-Ice-in-Water Cloud
