I'd forgotten what it was like to enjoy my science classes
Microbiology is AMAZING. We did an experiment in lab today that was so much fun Mark has offered to repeat it for the house if we set it up a week in advance. Basically, we froze ice with bacteria.
HOW IS THIS POSSIBLE? I shall tell you.
There is a bacterium that is known to cause frost damage. It enjoys snacking on the contents of cell cytoplasm. When cells freeze, the water within them expands, and the cell walls burst, which lets the insides out. Over time, this bacterium has developed the ability to induce water to freeze.
So in lab we took pure water, which has a freezing point of -15 degrees, and brought its tempurature down with an ice and alcohol bath to about -10 degrees. Then we took a dropper of the bacteria, dropped it in, and *bam*! Solid block of ice. It bloomed. Was so awesome.
Apparently this is exactly how they make artificial snow.
I love science.
