Sometimes you have to smell things in labs. It is very dangerous to stick your nose over a test tube and sniff it so you have to waft it. You do this by holding the test tube or beaker away from you face and wave your hand over it trying to wave the smell towards your nose.
It mean that you take whatever you are supposed to smell and wave your hand over it and towards your face rather than sticking your nose directly over what you are smelling.
You should waft a chemical when you want to test its odor or if it appears to be harmful. Wafting involves gently waving your hand over the chemical to bring the odor towards you without directly inhaling it. This method helps you assess the smell without breathing in potentially harmful fumes.
If you don't waft in chemistry, you could inhale potentially harmful fumes or gases directly, which could lead to respiratory problems or other health issues. Wafting helps to gently move the vapors towards your nose to detect any odors without directly inhaling them.
There are several synonyms for the word wafting, some of which include drifting, blowing, transporting, and floating. Wafting is used as a verb.
The method used to detect an odor is through olfactory receptors in the nose that detect airborne odorant molecules. These molecules bind to the receptors, triggering a signal to the brain that is interpreted as a specific smell.
