What happens when you drink through a straw?
This question points up some key misconceptions about what a vacuum is.So you put a straw in your cup of water. If you look down the straw or could look through it, you would see that the level of water inside and outside the straw are exactly the same. This is because the atmosphere is pushing down on the water inside the straw, and it is pushing down equally hard on the water outside the straw. So the pressures are equal.When you suck on the straw, you are decreasing the pressure in your mouth and lowering the pressure of the air in the top of the straw. When that happens, the force of the atmosphere pushing on the water in the glass is higher than the force of gas inside the straw. The atmosphere forces the liquid up the straw into your mouth. So, in essence, you ARE NOT sucking the liquid into your mouth, the atmosphere is pushing it there.This is easily proved by an experiment. Try drinking water from a straw that is more than 20 meters tall. It won't work. At around 20 meters, the massive column of water inside the straw would be pulled down by gravity, with a force greater than the upward force caused by the atmosphere. Even if you completely evacuate the straw with a high-powered pump the water won't make it up the straw. This is why you can't pump water out of a well that is more than 20 meters deep in the ground. Anything deeper than that and you need to use a compressor to pump air at high pressure down into the well, to force the water out (essentially make the upward pressure higher than the atmosphere alone provides), or revert to the tried and true method using buckets.Of course, a similar principle applies with underground or artesian wells. The water there is already under greater pressure and will flow to the surface if given a path.

How do cow dung and vegetable waste change into manure?
They don't. Manure is just cow dung and vegetable waste mixed together. Nothing more, nothing less. There is no change.Answer 2:They get broken down by microbes through the process of decomposition and fermentation. But really, both of these things are a form of manure. But they're not real manure, since you need to mix soil with these forms of waste in order for them to actually be a form of manure, and for the process of decomposition and break-down to be complete.
