i am assuming that you ask if you can cut onions under water... it is a waste of time. onions float and get slippery when wet so you will probably wind up cutting yourself, and still get burning eyes.
No, because the onion juice would dissolve into the water and fish don't even have eyelids anyway because their eyes aren't like human eyes.
you poo
You do not need to put an onion root in water, also cutting its roots would not have done any favours to the onion. If you keep the onion in dry and aired environment it will start to sprout naturally and can then be planted.
it turns purple and under a microscope you can see swirlys
The water turns purple and the skin turns white.
Questioner: Please see the comment page.
Osmosis takes place. The onion cell will turn flaccid due to the water loss.
they will disintegrate and soon the onion will peel and the onion part will BE NO MORE
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? What happens? The world may never know!
It either floats or sinks...put the marbles in water to test them!
