Q:
For a maths homework task, we had to write a method to find the weight of a rainbow. How silly is what everyone first though but iof course homework is compulsory so, I came up with the idea that: On a very sunny day, I could run a hose with a sprinkler on the end and when I see a rainbow appear, shout to my friend to place a measuring jug under the spray of water and collect it for n seconds. I could guesstimate the median length of the arc and the depth, and then guesstimate the area. I could then look at the amount of water collected and divide this by the surface area of the rainbow to give the weight of 1m2of a rainbow.
What do you think?
