In an earlier post I said that kids are the best experimenters. This seems not to be entirely true, as you can see.

Another observation: when kids play, parents start making up rules. “You can only bounce balls off that wall”, “Only throw the soft balls”. No doubt they don’t want their offspring to break things – which I appreciate – and they can see trouble coming far before the kids even think about things going wrong.

Another observation: the human form is very complex.
