Try this salt-water science trick at home! You’ll need: food coloring, salt, ice, 2 glasses of water 1: Add salt to one glass. 2: Add ice to both glasses. Wait 1 minute (don’t stir). 3: Squeeze food coloring into both glasses. Watch what happens! What’s going on? Salt water is denser than plain water. In other words, it has more stuff packed into the same space. The ice-and-color layer is mostly plain water. The denser salt water pushes up on the plain water, and the color floats! | KiwiCo
