- 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).
- Your brain is constantly eating itself. This process is called phagocytosis, where cells envelop and consume smaller cells or molecules to remove them from the system. Don’t worry! Phagocytosis isn’t harmful, but actually helps preserve your grey matter.
- Animals can experience time differently from humans. To smaller animals, the world around them moves more slowly compared to humans.
- Salamanders and lizards, for example, experience time more slowly than cats and dogs. This is because the perception of time depends on how quickly the brain can process incoming information.
- Water might not be wet. This is because most scientists define wetness as a liquid’s ability to maintain contact with a solid surface, meaning that water itself is not wet, but can make other objects wet.
