This hissing, bubbling Alaska lake is frightening scientists

I'd be frightened too if a lake started hissing at me.

Scientists are not easily frightened. They are the kind that run towards the erupting volcano.

It's a natural process. Leave it alone.

I wonder what it would be like to go for a swim

I would not.

If while you're swimming there's a significant-enough release of gas in the water around you then you'll lose buoyancy and find yourself drowning.

I wouldn't really start worrying until it starts to spit at you......

Light the methane on fire before going in... this heats up the water a bit and makes it more comfortable.

And I could fart with impunity whilst in the water, and you'd never know it was me...

You know that methane is odourless, right?

I do. I was thinking more about the bubbles....

Your smile would give it away!

Your smile would give it away!
That could be misleading.... I could be peeing! (although at the temp the water is probably not)

Ok Double l, now I remember where I've seen you before.

Not nearly as frightening as those African lakes that fart 20 ft deep clouds of CO2 and whole villages smother in their sleep.
Imagine being sent to investigate why no one is answering calls and driving through fields of dead cattle to find everyone there dead in their beds....
