Mary is learning some simple science -
Hard gel beads that turn into a Jell-o type matter when soaked in water.
She observed the sound of the hard pellets, felt them.
Then a day or two later, voila - smushy, mushy, cold, swollen, seemingly multiplied conglomeration of 'stuff".
It amazes me
Don't be overly impressed. Some of our little learning experiences last about 1 minute 15 seconds.
Often - it's merely exposure to "what can happen", what are some cool vocabulary words here, and what can we do to think and/or have FUN.
