Demonstrating chemistry - spectacular experiments. Sodium ethanoate stalagmite. 6
Description
Prof. Hal Sosabowski demonstrates a solid spontaneously coming out of solution in this visually beautiful experiment. Just a few crystals are enough to form a nucleation site for a super-saturated solution of sodium acetate. This self-perpetuating reaction forms the basis for hand-warming packs. Prof. Hal Sosabowski is a committed chemistry educator, evangelist and communicator. Hal shows us how to safely recreate his inspirational demonstrations, which are both educational and spectacular.
