We had some spare dry ice lying around recently, so we thought we’d take the opportunity to show some really cool (-78.5°C to be precise) demosBut what actually is dry ice?Dry ice is solid carbon dioxide which freezes at -78.5°C and goes from a solid straight to a gas in a process called sublimationCarbon dioxide is used to put out some fires It displaces oxygen from the fire triangle - no oxygen, no fireCarbon dioxide has a density of 1.98 kg/m3, which is about 60% denser than air Dry ice can be a lot of fun - watch this video for more demos and super satisfying giant CO2 bubbles popping: https://www.facebook.com/royalinstitution/videos/303097717082898/ -- source link
