In Prelims-2010, UPSC had asked about principle of Sugerfree (Artificial sweetener).
So based on that here goes some more; which of the following is true?
What is the Principle behind Mosquito repellent cream? (Odomos)
1. It contains a special volatile chemical that creates burning sensation in mosquito’s respiratory system and eyes.
2. It contains a chemical that masks the distinctive body odour that human skin emits, making you virtually invisible to mosquitoes.
(Correct answer #2)
How does diabetes glucometer work ? (Waseem Akram’s Accucheck meter ad)
You put blood drop on the strip. Strip contains chemical compounds: chemical reaction, color change. The glucometer measures the color-intensity and gives you the blood-glucose measurement.
Home Test kit for Pregnency (Accutest Cadila)
It detects the amount of HCG ( Human Chorionic Gonadotropin) in woman’s urine .
The levels of this hormone rise after the embryo has been implanted in the womb and the strip changes color after chemical reaction from urine drops.
Anti-perspirants (that John Abraham’s ad)
Basically the aluminum chemical penetrates the armpit cells and makes them swell hence the sweat cannot come out.
Emergency contraceptive pills. (i-pill, Piramal Pharma)
They contain same hormones as in normal contraceptive pills but in heavy concentration and hence prevents fertilization.
Instant Hand sanitizer (Lifebouy, Dettol etc)
They Contain alcohol (not soap). Alcohol destroy the baterial cellmembrane and then evaporates. So you don’t need water to wash off your hands.
Mortein Rat kill cakes. (why Chuhe mare baahar jaakar?)
Not very sure but apart from poison, it contains a chemical that makes Rats thirsty hence they run out of house in search of water.
I’ve given direct answers above, but UPSC is notorious for
adding ‘almost genuine and valid sounding’ false options in the answers,
so as I said in the Aukaat, Accuracy and Aim: don’t push your luck, if you don’t know the exact answer: just leave it.
Some more products (you dig):
- Hair Colors with and without Ammonia (Laurel Paris etc.)
- Goodknight mosquito coils, liquid vaporizers and silvermats.
Let’s brainstorm, please add products and principles from your side!
