Going to extremes

Doing measurement of g by dropping a ball using the Pasco kit. Thought it might be an idea to try with the longest drop possible so I sent a couple of students outside. I think they knew there was a photo opportunity coming up. Slightly concerned about Sasha standing on the railing, he only just got rid of his crutches from an earlier accident. Risk takers and all that.
