When you suck on a straw the pressure at the top of the straw becomes lower than the pressure at the bottom, which forces liquid up.

How do you make a straw that won't work?

Sabotaging a StrawPutting one or more pinholes in the straw, above the level of the liquid, will allow air to enter the straw at the top, and the liquid will not rise in the straw. To use this "sabotaged straw", merely switch ends (flip it over) so that the pinholes go under the liquid.


How can you make fluid flow up a straw?

One way to make fluid flow up a straw is by creating a vacuum by sucking on one end of the straw. This reduces the air pressure inside the straw, allowing the higher external air pressure to push the fluid up the straw and into your mouth.


Would it be possible to drink from a straw a mile long?

Yes, but it would have to be tilted, almost flat. You can only drink through it if your mouth is not more than 33 feet higher than the surface of the liquid that you're drinking through the straw.


When you suck from a straw you make your mouth bigger so what happens to the air pressure in your mouth?

When you suck from a straw, you increase the volume of your mouth. This decrease in pressure inside your mouth creates a vacuum that draws liquid up the straw.

Assuming that you could survive in outer space without a space suit would it be possible to drink using a straw explain y or why not?

No. The action of a drinking through a straw is that you suck the air out of the straw, and the air pressure on the outside of the cup them pushes the liquid up the straw. If there were no air pressure on the surface of the liquid, then there wouldn't be anything to cause the liquid to rise. However; 1. If there were no air pressure, the liquid would boil and vaporize; there wouldn't be any liquid to drink. 2. In weightlessness, you can't suck water through a straw even IN atmosphere; the liquid forms globules under the influence of its own surface tension. On the Space Station, the astronauts drink from sealed bulbs; sort of like juice pouches. You squeeze the pouch to push the liquid into your mouth.


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 can you made your own homemade Thermometer?

To make your own homemade thermometer, a person will need a plastic bottle, a clear straw, some putty, water, rubbing alcohol, and food coloring. Fill a quater of the bottle with equal parts water and rubbing alcohol. Add a few drops of food coloring to help see the change in temperature. Place the straw in the bottle and seal the top completely with the putty, making sure the bottom of the straw does not touch the bottom of the bottle. The liquid will rise and fall through the straw when the temperature changes.
