Dry ice: extreme freeze

Dry ice, or extreme freezing!
Reagents and equipment: glass container, dry ice - solid carbon dioxide, isopropyl alcohol, flower, candy, banana.
Put some dry ice in a glass container and add some isopropyl alcohol. The liquid’s temperature will drop rapidly. Immerse a flower in the mixture and wait 1 minute. The flower promptly freezes and can be crushed by hand or shattered with a hammer. Dip some candy into the cooling mixture – it turns from soft and stretchy into a cold аnd solid stone. The same thing happens to a banana. It’s a total freeze!
Dry ice is solid carbon dioxide. It forms at a temperature of -78.5 °C (-109°F). At room temperature, dry ice transitions rapidly from its solid to its gaseous state. Adding isopropyl alcohol to dry ice makes the liquid cool very quickly ⏤ the mixture's temperature can reach -90°C (-130°F). At this point, the water inside the flowers, candy, and banana quickly freezes and turns into ice, making these objects “stony.”
Safety precautions: Do not attempt! Perform this experiment only with professional supervision.
