When the phone peeped with that distinguished tone announcing the arrival of a new message on WhatsApp, I rushed to read it, and it went like this: “Please read and forward; A researcher in the United States has discovered a new type of cancer. This cancer is caused by Silver Nitro Oxide and it is the silver layer you scratch off with your nails when you buy a new recharging card. The particles of this substance goes under your nails and it end up causing you a skin cancer.”
There are a number of options you can take in a situation like that; you can believe and spread it, and in that case, you may never buy a recharge card again along with the hundreds who received your forward. And there is the other option; finding the truth.
The message above is a hoax. The matter we scratch off recharge cards has nothing to do with Silver Nitro Oxide, it is made of a specialized latex ink.
