Mrs B came up with the idea of using a weighted bucket as a primitive rain gauge to measure the weekend's deluge. This is what we made on Friday. The sides of the bucket are almost straight-sided. It would be important for the hole at the top to have the same area as the bottom. I put the cover on to stop leaves and stuff like that blowing in. The rocks are to stop it blowing away in the gales. I lifted them out to measure. It collected 60mm over 12 hours on Saturday night - that's wet. It is very open and could be susceptible to evaporation problems in strong wind and strong sunshine. I should work on a more conventional design.
