A Random Experiment ...

Spent the morning working on my Homework and then got ready and went to the university where I spent some time with some students helping them to make a TEDx opening video. It was fun and while experimenting, we tried this with a flashlight. I like this experiment. This is Zoia posing for me. Then we had a departmental meeting after which I bought a birthday present, picked H and went to M (S's son's) birthday party. Just returned and now am very tired.
