Farms do not grow straw. Straw is the residue from cereal crops like wheat, barley, rye or oats. After the grain is harvested in the combine and the chaff, which is set to not be spread by the chaff spreader on the rear of the combine, is "dumped" out in a swath out the back. A tractor with a baler implement attached on the back (same baler that is used to bale up hay) gathers up the straw with the pick-up reel and packs and makes it into a straw bale.
he rubbed amber and it could pick up pieces of sticks, fur, wool or straw!
The power of suction is what is demonstrated by water moving up a straw. When you suck through a straw, the water has nowhere to go but up.
When we suck the straw, we create a pressure within the straw to go against gravity. So the straw pulls up the lemonade because of the force we create through sucking.
When you suck from a straw you create a partial vaccuum which reduces the air pressue inside the straw. The air pressure outside the straw pushes down on the milk and forces it up through the straw.
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.
1) Air inside the straw moves 2)Pressure inside decreases 3)Pressure of the atmosphere is greater then the Pressure inside the straw=Liquid moves up the straw!!!
yes <><><><><> Actually, the pressure outside the straw presses the fluid up into the straw.
Suction.
A philosopher named Thales discovered it when he rubbed a cloth on a hard-fossilized material called Amber it would pick the straw in his barn up.
As you have more than likely taken the juice from the fridge, when you inserted the straw you have created a way the juice can escape. (usually by you sucking on the straw) But as the juice heats up, it also expands slightly causing pressure to build up in the juice container and forcing it to go up the straw to find a way out.
Because you suck it up
