Continuing on from our previous dry ice experiments – this is what you get when your sons have a geeky aunt…
Read this! Dry ice safety information:
- direct skin contact with dry ice causes the same damage as a heat burn – always use protective gloves when handling dry ice
- keep the room well ventilated because carbon dioxide from dry ice displaces oxygen and can lead to a suffocation hazard
- do not store dry ice in an air tight container because the pressure from the carbon dioxide gas can cause the container to explode
- do not store dry ice in your freezer because the extremely cold temperature will cause the thermostat to shut off the freezer
