  1. “and how to make it” no instructions given.

    So I will give them!

    To make sodium acetate you only need baking soda and vinegar. Add vinegar to a beaker (or clean glass container) and warm it up, then add baking soda scoop-wise until the foaming stops (the liquid will likely turn brown, this is due to impurities in the vinegar and will not effect the resulting solution).

    Once the baking soda stops causing foaming raise the temperature of the mixture to a low simmer (the colour may darken, again, not a problem). Once you start to see crystals form remove from heat and let cool. You should have a brownish solid block that looks like the crystals above. Scoop out some bits of crystal for later (a few grains).

    To melt it, add around 10 mL of water and warm it back up. If all the crystals don’t dissolve add more water a mL at a time until they do. Remove from heat and let cool. You should have a lovely fluid with no crystals in it.

    To activate crystalization shock the container in some way, either by touching it, slapping it with a spoon, or adding the crystals of sodium acetate you gathered before melting it.

    The recrystalization will be fast and quite exothermic (warm!). It is repeatable by melting the solid solution again and adding water to ensure the melt is complete. It is infinitely repeatable as long as you keep the final solution saturated. If you find you’ve added too much water just boil it off as before.

    Ta da! Your own sodium acetate to play with 🙂
