Today happily messing about with various things - and a visit from the young bloke was fun too. Took happy snaps to keep everybody happy. Next time the lad is in such a good mood I will try something more interesting. But the adults had coffee and cake, and the lad had a new toy. He also has 2 teeth. I tried in vain to get a proper look at them with the lens! He is now also well able to reach out and try to grab things including lenses.
He was not screaming just sort of laughing.
After yesterday's pencils I attempted to add a further challenge - reflections on small things. Not solved this one yet.
