Do empty, sealed glass bottles float on water?

[Mr_Dangerous]

Any opened bottle will sink when thrown in the ocean, because water goes in the bottle making it heavy, simple. And we all know that an empty closed plastic bottle will float 100%

But If I were to throw a sealed empty glass bottle in the ocean, would it float? Or sink?

I am confused because glass bottles are usually heavy so I am not too sure.

A sealed glass bottle of any ordinary size will float. Objects sink until they are taking the space of water equal to their own weight. An sealed empty quart bottle that weighs two pounds will sink until it is occupying the space of two pounds of water. As a quart of water weighs about four pounds, it can sink no further. if the seal fails and the bottle fills then it will only be taking the space of the glass and will sink.

[Mr_Dangerous]

oh wow thats crazy. So for example, If I drop a very heavy metal bottle thats sealed and weights around 8 pounds, it will sink until the water above it is ~8 pounds?

A huge cargo ship made of steel will float until it’s filled with water. Yes, sealed, it will float.

[Mr_Dangerous]

Makes sense.

[douride2]

Yes they will float. It's the air inside the bottle that does it.

[Mr_Dangerous]

awesome! Thanks

it of course swims. that's why letters in a bottle are a thing.

[Mr_Dangerous]

Exactly my project here, you're right on the money ;)

I'd hate to use plastic so I am resorting straight to glass.

[genericname85]

well if you're using it for that purpose, plastic doesn't break on impact on rocks or whatever xD

[Mr_Dangerous]

True that, the idea you say is flawless and fail proof. But I'd prefer to stick to nice clear glass wine bottle, corked up with a message in it. I'm not environmentally correct myself, id do it to make it work, but I prefer it to be very classic, as it was for centuries. Plus it looks dope haha feel me?

[genericname85]

Yeah. I actually found one before, while canoeing down a tiny river near n home village xD turns out it was one year old but only made like 3 villages distance. 10 miles a most, before it gets stuck.

[Mr_Dangerous]

Far enough for me, we got islands around here man. Long Island, New Jersey, Staten Island and many many more beaches.

cool

[Mr_Dangerous]

kool

How are you 19 and don't understand displacement. Floating has nothing to do with weight. Otherwise ships wouldn't be able to sail.

[Mr_Dangerous]

Hey! I never took interests in physics, now learning haha

[Quackthulu]

But you still finished elementary school, right?

[Mr_Dangerous]

No Dick, I'm in college.

[Quackthulu]

Huh, how'd you do that without finishing elementary school?

[Redstang88]

It would still float

[Mr_Dangerous]

Great! Thanks.

[Likes2drive]

It will float

[Mr_Dangerous]

Thanks!
