“Banana” flavouring is based on an extinct type of banana
Ever wondered why banana-flavoured drinks and candies taste absolutely nothing like a real banana? According to some people (although it can’t be verified for sure), artificial banana flavouring was based on the Gros Michel variety, which is said to be sweeter and more pungent, almost “fake” tasting. It was thought to be extinct but there are a few places in the world it is still grown so you can taste and decide for yourself!
“Octopi” is not the plural of octopus
Hang around a know-it-all long enough and eventually, you will hear someone corrected when they try to talk about more than one octopus. Many people think the right plural form is “octopi” but based on the Greek roots, it technically should be “octopodes.” No one says that, however, so grammarians have settled on “octopuses” as the correct pluralisation of octopus. Yep, it’s exactly what you always thought it was! As for “octopi?” It’s not even a word.
A number that will blow your mind – literally
Graham’s number is a number so large that a digital representation of it cannot be contained in the observable universe. Scientific humourists joke that if you actually tried to write it out, it would cause a tear in the space-time fabric, causing your head (and everything, really) to explode.
