It is a well known fact that the cleaner the water is the stronger the ice will be.
we did the in a highschool lab. our mediums were one gallon milk jugs used as flask [ul] [li]clear tap water (unpurified/no salt)[/li] [li]salt water (a pinch of road salt which is the closest to natural salt found in the environment)[/li] [li]pete (black dirt from the bottom of a lake)[/li] [li]sand recular off the bottom of the lake[/li] [li]flower (all perpous, no yeast soda or other riseing agents)[/li] [li]one with a fish aquarium bubbler simmilar to those used in cenerated by a DC power unit wired out side of the freezer.[/li][/ul]
Our test ran 6 hours of freezing. we had seven class per day. the first class at the beginning of the class plased the materials in a flask. each with its own properties. and shaken to the point of emulsion of all materials. including the one with no additives.
7 trays were prepared. each containing a sample flask of each senario.
we had 6 teams one for each medium.
each flask was placed in a walk in freeser at a controlled temp of 32*
exactly one hour intervals one tray with the controled mediums were taken out and tested. for hardness.
each team of each class had a sample to to pull from the freeser and make a report of their findings.
the final being exatly 24 hours of freezing temps.
I wont boar any one with the results of the samples,
I will give you the results of the testing as a whole and they remained the same through the entire test.
at the end of 24 hours the lids were removed and droped from the top of a 10 foot step latter. frose or not. [ul] [li]clear tap water (unpurified/no salt) nearly busted the milk jug during freesing prossess, for the most part stayed together.[/li] [li]salt water (a pinch of road salt which is the closest to natural salt found in the environment) frose but was weekand crushed on impact. [/li] [li]pete (black dirt from the bottom of a lake) never frose solid (like a slushy drink)[/li] [li]sand recular off the bottom of the lake froze solid[/li] [li]flower (all perpous, no yeast soda or other riseing agents) frose but not solid[/li] [li]one with a fish aquarium bubbler simmilar to those used in cenerated by a DC power unit wired out side of the freezer. never forze[/li][/ul]
