When it rains, it can often rain for a long time – we’ve all got wet being outside in the rain for too long! This rain comes from clouds in the sky, however this must mean that a cloud must be made of all of the rain water which falls on us – that’s a lot of water! So how much does that make them weigh?
This fantastic video by Robert Krulwich from NPR explains how heavy is a cloud is, and how heavy a hurricane is.
