Magnetometer dig
Four students met up after school on Wednesday 16 July, and started to dig a hole to bury the magnetometer in (it is enclosed in a drain pipe but still needs to be buried in order to reduce temperature variations at the sensor which would affect readings). After two hours, they had dug down to about 60 cm—20 cm short of the required depth—with progress being slow owing to tree roots and rubble from when the languages college was built.
