Tom Scott: Things You Might Not Know

There's an urban legend that poppy seeds can make you fail a drug test. Is it true? And if so: why? I ate a few bagels, and set out to flunk an opioid test.

Torpenhow Hill, in the Lake District in the north-west of England, is the only place in the world whose name has the same word four different times. That's the story, anyway. The truth is a bit more complex.

he Orkney Islands, off the northern tip of Scotland, have so much electricity that it's actually a problem. Here's why: and here's what they're doing about it. • This video has a correction: Hornsdale Power Reserve didn't catch fire! It was the newer Victorian Big Battery, near Geelong.
