Ken, Katie, and Lizzie spent a good portion of the day trying to make supercooled liquids turn into instant slushies. They watched YouTube videos. They walked to the store to get bottles of tonic water and Sprite. While the liquids chilled, they made corn starch ‘magic mud,’ and talked through the science of molecules lining up when they freeze, but sliding around in a liquid. And at 8pm tonight, after two fails and a family bike ride, they tried it one more time.
Together, we watched the supercooled liquid freeze instantly.
And together, we at the slushy with three spoons. Good stuff.
(Nope. Not what ours actually looked like. But, to the kids, I think they seemed just like this.)
