Instant Ice

There is this really cool chemical called Sodium Acetate. For some reason, when it is dissolved into water, then cooled down, it becomes sensitive to the touch. When you disturb the substance, it will instantly crystallize and become very warm. This is known as an exothermic reaction, because it gives off heat when taking place. Below is a link to a video that we should be doing. We should be performing the experiment in class tomorrow, so be there to see something really cool. And a big shout from Mr. Harrelson's last class of the day, WE ROCK MORE THAN YOU DO!!!!!!!!!!
