A seed crystal can be dropped into a saturated solution of sodium acetate. The solution will suddenly crystallize and turn to solid. Alternately, the solution may be slowly poured out onto a seed ...

A reusable hot pack made of a supersaturated sodium acetate solution that crystallizes spontaneously once triggered by a metal piece releases heat. A balloon filled with hydrogen gas also releases ...

A heat pack is a commercial product used by hikers and skiers as a hand warmer. It consists of a plastic pouch filled with a supercooled solution of sodium acetate (NaCOOCH 3). When a metal disc in ...

It's time for another amazing experiment with Amy, Mark and Zoom aboard the spaceship curiosity on RTÉjr science show Let's Find Out! It's made with the help of Science Foundation Ireland and it helps ...
