How much does a cloud weigh?

How much does a cloud weigh? - BIONBIT

If all those elephants were hanging out in the sky, they’d fall. So how does a several-hundred-ton cloud stay afloat?

Here's Why - The weight isn’t concentrated in a hundred elephant-sized particles or even a billion marble-sized ones. It’s distributed among trillions of really tiny water droplets spread out over a really big space. Some of these droplets are so small that you would need a million of them to make one raindrop, and gravity’s effect on them is pretty negligible.

What’s more, the cloud is less dense than dry air, so it's buoyant. It also helps that all those little droplets get some lift from updrafts of warm air. Those droplets don’t float forever, though. When the cloud’s water density increases and the droplets get bigger and heavier, the cloud eventually does fall, bit by little bit, in the form of rain.

'I Left My Husband For Him, But He Didn't Return The Favor'

Sometimes we screw up, but we have to find happiness and strength within to get back up again. If someone had walked up to me and told me a year ago I would be a 30-year-old single mom with two kids, I would have looked at them like they were batshit crazy. A year ago, I was THAT mom -- the one who seemed to have it all together, who had it all in some ways: two beautiful boys, a nice home, a good man and father to our kids. I cooked the meals and coordinated professional family photos, planned vacations, sent out Christmas cards, etc. I had a rigid schedule but made time to run and managed to be in decent physical shape. But something was missing. In my marriage, I felt alone. Why wasn't I happy? I met my ex when I was seventeen. He was four years older than me and I was smitten. He had a job, a truck, and a house. He had it all together. We got along great so dating him while I was in college seemed like the right thing to do. And of course, after college the next step w...

Nutcase Couple Hang From Cliff 2700ft Above Rio

While most people get a little bit worried about heights when climbing up a ladder, Leonardo Edson Pereira, 23, and his girlfriend Victoria Medeiros Nader, 18, are very different. In fact, after seeing images of the couple hanging off a 2,700 ft cliff in Rio, Brazil, it’s safe to say the couple pretty much break the mould when it comes to heights and being daredevils. Pereira took his girlfriend with him on his latest thrill seeking adventure, with Pedra de Gavea their conquest this time. The images really are breathtaking and depict just one of the many times Pereira has climbed the Pedra de Gavea. He claimed: "I love living on the edge! I know people think it’s dangerous and crazy but it makes me feel alive,’ Leonardo says. It is really high and I do just hang on using my arm strength. I have to trust myself not to fall." The literal translation of the rock’s name means ‘Rock of the Topsail’, and while the images certainly are something, given ...
