SMMART SCIENCE:Negative Space Ice Sculpture
She fills a glass with water and pops it into the freezer. Then she comes back to check on it periodically to check the progress. She loves when there is just a thin film of ice over the top and the water is still liquid underneath. She breaks through the ice and eats off the thin shards.
My favorite is when she leaves it just long enough for all of the sides and top to freeze, leaving liquid inside of the icy shell. When she lifts the ice shell, the liquid water drains and a beautiful negative space ice sculpture remains.
A fun way to talk about the many phases (liquid to solid) that water undergoes. Have you seen the many silicone molds that IKEA has? Those are super fun to make ice!
