A cloud weighs around a million tonnes. A cloud typically has a volume of around 1km3 and a density of around 1.003kg per m3 – that's a density that’s around 0.4 per cent lower than the air surrounding it (this is how they are able to float).

It’s impossible to hum while holding your nose​

You just tested it, didn’t you? Normally, when you hum, the air is able to escape through your nose to create the sound, and of course, it can’t do that when you’re holding it shut. This is one of the weird facts you can test out for yourself. Go ahead, try it.
