I set up a giant tub on a bright white plastic sheet. I had Biscuit pour water into the tub and choose what color beads she would like to play with. Here is how we started....
We had small dark blue, yellow, and red beads.
After about a half hour they looked like this...
They were a bit larger and the colors were changing to a lighter shade!
It was soon time for Biscuit's nap.
After two hours she came downstairs to find the little tiny beads completely transformed.
She said "WOW, they are marbles now!"
She was also thrilled that the red beads were now pink.
We scooped the beads out of the tub....
and dumped them into her light table!
This activity was a BLAST.
