After a kids chemistry day at a local college; home chemistry became all the rage for a day or two. Here: writing with radishes on baking soda-painted index cards.
With Daddy in the Idea Factory; just before I returned to the Fairy Castle, where I fell in love all over again. The last time I saw it was as a child.
