In england, do they swim on the left side of the lane?
I live in England and we circle swim like the Americans do.
Someone tell me the different between hot ice and dry ice ?
Hot ice is a mixture of Baking Soda and Vinegar .. warmed up. You get CO2 given off as a gas .. and a solid that looks like slushy ice that rapidly expands .. and it's HOT. Dry ice is frozen Nitrogen. As it warms up it turns back to a gas without going through a liquid stage that's why it's called ''dry'' ice .. and it's VERY COLD. Neither would make a swimming pool colder but dry ice would produce a lot of 'smoke' and would 'boil' in the water producing a 'volcano of bubbles'. EDIT .. I've just comeback to this question because I realised I'd put Nitrogen and not Carbon di Oxide for dry ice. billruss ... is right. Ignore the thumbs down.
