Taught Ray how to elicit toots from a bottle today.

As always, the experience of successfully teaching something comes to me as a miracle: I say stuff, and suddenly the light goes on, but the connection between the two isn't as straight a line as the ego would like.

She did the work. I just babbled about blowing straight across, like the top of a drum, to make echoes that are smooth and run together. It was only the doing that made it make sense.

Here she comes with the bottle again :)
