Since tears come out of your eyes, you could technically get your eyes removed so you could not physically cry anymore :)
Yes, boiling the onion can prevent crying
You wont get same taste of onion if you boil it. But yes it will prevent you from crying.
The dependant variable in this experiment would be the amount of 'crying' resulting from the cutting of each onion.
yes if you put the oniion in the freezer 10-15 miutes before you use it ,it prevents you from crying
is order to avoid crying 1.wear glasses 2.wash while cutting
When cutting onions, cells are broken, releasing certain substances that are modified and then reach the eyes through diffusion, where they cause irritation on contact. To prevent the eyes from watering, you have to prevent the gas from reaching them - for example by cutting the onion underwater. Chewing gum might help a little if you chew with your mouth open and also breathe through your mouth. You will simply disturb the gas's diffusion this way.
Yes it would. The volatile oils in the membrane between layers of onion make your eyes water, provided the onion is sufficiently warm; if the onion is cold the vapours won't be released during cutting. For this reason, onions should be kept in the refrigerator; store them in a plastic bag, twisted to keep out the air. You can put them in several layers of plastic bags, or in a tightly-sealed plastic container so that they don't cause your refrigerator to smell of onions.
I assume your asking "cutting onions", The simplest way I've noted is to turn on the stove fan and let it pull the air away from you as you work on cutting the onion and then wash your hands and tools used.
you cry when cutting onions because the chemical from the onion is attracted to moisture, and so as your eyes are full of water the chemical will irritate your eyes and tear ducts. in conclusion, yes candle light MIGHT help as the flame will evaporates the moisture and yet it might NOT help as the flame cant take all of the moisture out of your eyes.

Onion:When we cut onion 2 chemicals like sulfoxides and enzymes to form gas when this gas reach our eye it makes cry now usually to avoid crying we wash the onion then we see crying chemicals if we make next onion we will wear goggles to protect our eyes thus gas do not reach our eyes.
no
Yes. Also, if you chew bubblegum while cutting the onion it is supposed to prevent you from crying
By microwaving the onion you will cook it, this will prevent you from crying when you peel it but will also spoil the onion. Try this instead peel the onions in a bowl of cold water or under a running tap, or peel them outside so the wind blows away the onion fumes. Or try an old wives tale which is to hold a tea spoon between the teeth in your mouth. Good luck.
