Proving through action

I was at the Jelutong market place this morning when I passed by a man who was selling abrasive sheet to clean the bottom of cooking pots. He told the crowd around him that the abrasive piece is very good as it can remove carbonised coating on the wok's bottom by rubbing it with the aid of water.

To prove that it is really water and not other chemical that he poured from his bottle, he drank the water first before pouring it onto the bottom of the pot he was dealing with. If you look at his action, you will surely be convinced that it is water all right and not chemical of any sort.

The man is really smart. He has proven his point in a simple way.
