"Don't boil a kettle on a boat"

Here's an oddly specific British PSA: Don't boil a kettle on a boat. What? I had so many questions. Is this a thing? Do boats really blow up when boiled water spills? Is this even a real public information film? It seems so dramatic and to the point. Ok, wait, it took me forever but I found a commenter on TikTok taking credit for it. Bravo, Michael Spicer, you really had me going! To be fair, real public information films are scary! (GreatBritishMemes)
