Over my chemistry teaching career, kids have clamored to make Hot Ice. The kids trying to make Hot Ice used lab grade sodium acetate. It never worked. Today, we tried Frugal Fun’s Hot Ice instructions using baking soda and vinegar. (Here is the balanced chemical equation.). I followed Frugal Fun’s Hot Ice instructions, even scraping crystals from the side of the pan with a butter knife.
Back to the fridge...nothing.
Back to the stove...surface of the moon. I added water and put the solution (mess) back in the fridge...
Crystals? Check. Hot ice? Not so much.
