RYNJ Students Do ‘Cool’ Experiment With Dry Ice

Using boxes of dry ice, RYNJ students learned that its properties consist of solid CO2 and then began their experiments. Students watched the dry ice subliming, which means melting straight from a solid form to a gas. Then, they dropped some of the dry ice into a vat of warm water and watched the sublimation process speed up. They also added soap to the water and observed the formation of gas bubbles which is a result of the gas within the liquid vaporizing. The bubbles are more breathtaking than regular bubbles because instead of regular air inside, it had a thick gray gas in the middle of the bubble. Afterwards, the students were able to touch (wearing gloves) the dry ice and slide it around. The gloves protected their hands from the extremely freezing temperature of dry ice, -109.3℉, which if touched with bare hands can cause frostbite.
