Keeping my up new thing of posting something to do with numbers every day

The total number of grains of sand on the Earth is roughly the same number (actually a little less, but not much) as the total number of stars in the observable Universe. Which is also the same number (roughly) as the number of water molecules in ten raindrops.

Quite staggering if you think about it.
