Another interesting characteristic is that ice takes the form of the container in which it is frozen. As a consequence, when the girl on the right pulls the ice out of the cup, it is the exact shape of the cup. If she wants to put it right back in the cup, she can with ease. Putting the ice in the container in which it was frozen now becomes a 3-D puzzle.
And some of those shapes can be very interesting, such as the little ice cylinder the child is pushing into and taking out of the plastic tube on the right.
Yet another unique characteristic is that it is cold. Children find out how cold it is and their tolerance for cold in different ways. They will usually use there hands, but some find other ways to experience the cold.
Gregory decided to feel it against his face. "Yes, it's cold." he said. In addition, he also found out how smooth it was on his face.
Of course, many children will taste it, too. It is a sensory table after all.
Speaking of smooth, Hannah found a superball that had been frozen in ice and decided to use it to make an ice ball smooth. I am not sure how she held the ice so long, but she was intent on making sure it was smooth. You can see the pride she feels about her accomplishment of making the ice ball so smooth.
