Mondays I check the level in our rainwater tank. It doesn’t rain much in the summer months here. I drop a plastic cup on a string till it touches the water, measure the string and do a few sums. We have less than 10,000 litres left, but good rain should come soon.

Water tank measuring kit: ball of string, small plastic cup, clip, tape measure.
