Experiment Girl - Salt on Ice

This is another experiment from Play Create Explore and it is really cool.  I loved watching the ice crack and pop and the colors expand and so did Charlotte.  Of course, she also enjoyed using an entire container of salt on the ice but enjoyment's the name of the game so that's ok!
