We've all seen a public bin before, and while some of them are quite obviously made of plastic, some of the models that are commonly painted black and gold have the appearance of being made out of metal.
But it turns out, they're not metal at all - and many Brits are only just discovering the truth.
The realisation was posted on social media after a member of the public spotted a broken bin in their local area, which had a hole taken out of the side of it, revealing that the bins actually appear to have a wooden interior rather than a metal one.
