This morning I dropped Nicolai, Mario, and Rory off at the Science Museum on my way into work. Here Nicolai attempts to bring the ends of two L shaped sticks together while looking through a prism which swaps right eye view for left. Quite an amusing challenge for one and all. I picked them up after work and each had to cite 15 science facts they had learned during the day before I would take them home. Fortuantely they were up to the challenge.
