Rocks

So sticking with the R theme, we collected "Rocks" and then washed them.

 

We used soap, strainers, scrub brushes, and towels.

This was a nice break from doing art! :)

Then we dried them and rolled them on an inclined plane too see which ones went faster.  They thought that was neat but wanted to keep washing them, so we did!

Something different that lasted an hour and a half!
