Honestly, every single scientific explainaition I have ever recieved on funnyjunk has been disproven in the comments, do scientists actually not know anything?

Hey just saying but you don't have to say objection if your picture already says it

im glad there are people like you to bust these ridiculous accusations

However, large methane bubbles are capable of capsizing smaller vessels, making them a risk anyways

Consider this; The gass from the whatever makes the crew high as fuck, and then they want to fuck mermaids and sink the ship on purpose to sail down to them and sex.

I was thinking more along the lines of a smaller decrease in density, meaning the ship goes a little deeper without the captain being aware. Therefore, he might think his ship is floating high enough to pass the sand bar, but because the density is slightly lower, it actually isn't and gets grounded.
Just my interpretation of the information, no idea if this is correct, but it sounds viable enough since it holds with Archimedes' Principle (less dense water = greater volume of ship needs to be submersed).

It appears I stand corrected. Thumb for you, good sir.

But what if there is a heavy concentration of methane vents in the sand bar? would that not be enough at such shallow compared to the rest depths to be able to sink a ship?
