This isn't fair, I'm from America. 😋
@benfrog ahaaa!  the ultimate guess!

@stux Note that the lead will leave a mark when dropped on your foot.

I need coffee. 😈 #SoMuchCoffee

@jan I guess that's true! but only on a planet, moon or other heavenly body I guess 
@stux the feathers, because one must also carry what happened to those chickens 😢
@dinandmentink Don't worry! It's old feathers only, they got new ones 😁
@stux just thinking about the amount of feathers I would need for 1kg. 🤯
@stux More correctly: they have the same mass. 😏 Weight depends on gravity. So 1 kg of feathers on earth weighs more than 1 kg of iron on the moon.
@rudymegens @stux Indeed. The #kilogram of #feathers has a lower density, so a larger volume. Therefore its center of mass will be slightly higher than that of the #lead and farther from the ground. That makes it slightly lighter.

@stux the other one we loved as kids was:

"If a plane crashes exactly on the border of Canada and USA, on which side would they bury the survivors?"

@ottaross Haha holy shit that's dark 
@stux it was the '70s, the trick questions were darker then.

@stux

The gram is a unit of measure for mass, which is the same whether the item in on Earth or in space or anywhere else.

Weight, or how heavy something is, is how much force it pushes down when it is on Earth (or another planet). A balloon filled with helium could have a mass of one kilogram, but weigh nothing because it is buoyant in air -- the air it displaces weighs more than the balloon.

The lead displaces less volume of air than the feathers, so the lead is less buoyant than the feathers. Since the feathers are more buoyant (even though they are still heaver than the air they displace), they will push down toward the Earth with less force, so they will weight less.

So the correct answer is one kilogram of lead is heavier.

@stux Let's ask ChatGPT. I've asked it something similar in the past, but about feathers and steel. And in silly units.

1) It "understands" lead better than steel.
2) It "understands" SI better than silly units.
3) It's a LLM and so "understands" nothing.

@stux You know nothing, ChatGPT.
@stux i m not a scientist, tell me.
@stux I can literally hear the scene...

@Weirdaholic @stux would've been different if it wasn't weight but volume...

But 'Muricans can't do metric...

@stux I'm sure there was a trick question about ounces that relied on different units of measure for feathers vs metals :)
@stux whaaaat ? It is not the feather 😱
See the _100 Humans_ episode on Netflix where they ask the weight of a TV displaying either clouds or bricks 😁

@stux

Thank you for this poll/puzzle. I found a video that explains the answer. It involves linguistics as well as physics!

A kilogram of steel IS heavier than a kilogram of feathers. Here's why.
