In this video I drop a few small sodium acetate crystals into a test tube filled with a supersaturated sodium acetate solution. We filmed this with a high-speed camera for our high school senior final "profile project'.
As the crystals are dropped into the solution you can see the solution begin to solidify instantly. The sodium and acetate ions in the solution begin to attach onto the crystal structure of the solid sodium acetate crystals.
There is a light placed under the tube which gives a more detailed view of what's going on.
