I genuinely had quite a heated argument with my old flatmate about this because he insisted on using metal cups for his drinks because, in his words, “it keeps it colder.” In culminated in me putting an ice cube on both a metal cup and a plastic one to demonstrate how it would melt faster on the metal one. After this experiment he grabbed both the cups and said, “yeah, but the metal now feels colder.” Honestly, I could have hit him 😂.

To play devil's advocate, the temperature difference would be small enough that any psychological effects would negate them. That is to say if he believes it, then he would be "more refreshed" by the drink in the metal cup. Just don't take him anywhere where it might be important to your safety 🤣

@@nicholascrow8133 haha, brilliant! We’re still friends 8 years on, so it’s all good and is kind of a running joke. I used to grab his thermos and go, “oh that doesn’t feel very warm, you’ve got cold coffee there!” 🤣

I got a question for you What eavier? A kilogramme of steel or a kilogramme of feathers. That's right, it's a kilogramme of steel. Because steel is heavier than feathers

@ScotchWhiskey864 3 месяца назад

What dya mean? They're both a kilogram But steel is heavier than feathers I know, but they're both a kilogram What?

The third law of thermodynamics. If you gained any brain cells watching QI clips, you will immediately lose them after reading RU-vid comments, hence achieving equilibrium.

Surely if you are holding both the wooden spoon is colder. Because the heat has conducted from the metal spoon to your hand more efficiently. Therefore your hand heated the metal. Assuming the room is colder than the human body.

@barneylaurance1865 3 месяца назад

Metal spoon is a reasonable answer, since "colder" wasn't precisely defined in the question. The metal spoon takes more heat from your skin. Neither is also a reasonable answer. The wooden seems to be the only clearly wrong answer.
