That's what 55m3/ second of water looks like

Lots of fun stuff today, a wander down to the river with James and some dimensional analysis in the car as well. James has been doing areas of a circle and volume of a cylinder at school, thus discussions over what cubic cm are and how it's the same as a ml.

As ever the boy ate well and we finished the day off with the second half of National Treasure as it went dark. A great day to be outside, especially after a few weeks of wet weather.
