Sand is not water

Today we took his ESL stacking cups we usually use in the bath to the playground. What a surprise for me that he did the same stuff with them like he normally does in the bath and whoops, there were no bubbles (those cups have tiny holes, so if you press the cup against the water, bubbles appear) or he was not able to get the cup under the sand just by pushing it down. So interesting to watch. He seemed to have a lot of fun discovering the differences, too. Then some older kids came, and smiled at him because he was tasting the sand, which encouraged him to eat more. Yay for sandy poop tomorrow! :)
