When I was in Portland, we went to OMSI

Rosie played in the sand. 

And she played with water.  Now that she is 2 she wears the red apron.  When she was little she wore the yellow.

She made things fly.

And the last thing Rosie did at OMSI was to play with Flubber.  I had never heard of Flubber but now I know it is the coolest stuff ever.  It reminds me of the green slime Gus used to have with his Ghostbuster's paraphernalia.  But Flubber can be made at home (there are plenty of recipes) and it is easy to clean up -- a huge improvement over slime which no doubt still lingers in the crevices of some old furniture.
