I don't get how this would be possible. I understand the lensing effect of a droplet of water, but wouldn't the heat it generates lead to it evaporating, thus removing the application of heat and stopping the process?

Never mind, I'm a retard.

However, the likelihood is reduced as the water drops should evaporate before this, so these claims should be treated with a grain of salt.

Fresh water is safe then?

Nah, you just didn't read the whole article. But, who does, really?

That's hot

you expect me to believe something like this posted to a sci-fi blog?
 
2010-01-11 04:34:54 PM
burnt leaves != forest fires. meh.

Sort of how I can shovel global warming off my driveay. Up is down. Black is white. I love the new science.

You don't water at midday because it tends to shock the plants, plus most of the water gets evaporated by the sun before it can be taken up. That's what mom always told me and her gardens agree.

Oh holy raptor jesus! A headline that is actually ironic!

Look, DHMO is dangerous stuff.

Is there a climate change corollary to Godwin's Law?

That's what I've been told as well. Who the fark doesn't water at midday because it might start a fire? My bullshiat detector is pegged in the brown.

The obvious solution is to pour fire on the forest, if this happens.

This is when you fight fire... with fire.

I thought Firewater was a native term for Whiskey.
 
2010-01-11 04:48:14 PM
But why bother - it's so much easier to use matches and gasoline...

A brief review...

Headline: "Water Burns!"
Article: "No it doesn't!"
 
2010-01-11 04:48:26 PM
Well, duh. Hydrogen is flammable, and everyone knows fire needs oxygen to burn.
 
2010-01-11 04:53:33 PM
we all know what causes forest fires

To water! the cause of, and solution to, all of a forest's problems.
 
2010-01-11 04:56:14 PM
So the moral of this story is that pissing in the forest wont start a fire, but it might burn some leaves?
 
2010-01-11 04:56:15 PM
It's like RAIIIIIIIIiiIIIIIIN, on a forest fire!

I got pegged in the brown too, It was definitely a shock how much got taken up.

Or, maybe the water droplets could get on some dried piles of material in the forest and start it decaying and generating heat. My neighbor started a fire in his compost pile that way by watering it.
/Cool Story!
 
2010-01-11 05:03:16 PM
Improbable!
 
2010-01-11 05:04:01 PM
how fast was it going?

It doesn't generate heat, just focus it. The focal point is outside of the droplet, so the droplet itself is still only receiving the same amount of radiation, but at the focal point it would be hotter. Water, being mostly transparent, does not absorb heat well from light.

Cue Republicans using this to push for unrestricted logging of every tree in N. America.

If it's really really hot water it can.
 
2010-01-11 05:07:06 PM
This is why you shouldn't water your lawn in the heat of the day. First of all a large percentage of the water evaporates. Secondly, the suns rays can actually burn up your grass through the droplets.

Merky: This is why you shouldn't water your lawn in the heat of the day. First of all a large percentage of the water evaporates. Secondly, the suns rays can actually burn up your grass through the droplets.

I thought you water in the morning and evening because the sun evaporates the water and the grass is unable to absorb a proper amount.

/wait are you joshing me?

Came for the pic of the water zippo; leaving disappointed.

Just like the lense of the magnifying glass doesn't get hot when you light sticks with it.

Do you often have the need to defend yourself against arson charges?

This reminds me of a couple of stories I've seen here about snow globes and glasses of water starting fires inside houses.
