Odd. I don't find it particularly fun and cannot remember a time when I ever did. I doubt I spent much time in childhood doing that.

However, one of my early pre-first grade schools had buckets of water and paintbrushes and we were allowed to "paint" the wooden playground equipment with them. I liked that, but I remember part of that was that the wood changes color when it's wet.

Also, looking back at that, I am somewhat amazed that we never threw buckets of water at each other. We always used that the way we were allowed to. It's one of the things I remember being very popular and thus in shorter supply at a school. The other thing (which may or may not have been the same school) were tricycles. We had a small number of them and everyone would race to try to get one. But it's not surprising that young kids like tricycles. I think most people assume young kids like vehicles they're allowed to drive.
