it turns purple and under a microscope you can see swirlys
they will disintegrate and soon the onion will peel and the onion part will BE NO MORE
When tap water is added to purple onion skin cells, the cells will undergo osmosis. Water will move into the cells, causing them to swell and potentially burst if too much water is absorbed. The purple color of onion cells may also diffuse into the surrounding water.
Nothing noteworthy happens if mentos are put in tap water; they simply dissolve slowly.
put two wine corks in the boiling water and one onion! all done.
water will put out fire
It will make the water white
What happens is the alcohol starts to shred the onion. Next alcohol is soaked up inside the onion which starts to make the onion shrink. The cell can't take the acid that goes in it shrinks and dissolves.
When you cut the onion root and place it in water, the root cannot continue to grow because it has been severed from the plant's vascular system which carries nutrients and water to the root for growth. Without this connection, the root lacks the necessary resources to regrow.
It either floats or sinks...put the marbles in water to test them!
nothing
it floats
