It is an iron bar of 1000 grams, which means 1 kg. Its purity is 99.99% and its current market price is only $100. The funny thing is, ⛔ If you use it to make a horseshoe to protect the horse's hooves, it can cost $250. ⛔ If you make a sewing needle with it, it can cost $70,000 ⛔ If you make a watch spring and its parts with it, it can cost 6 million dollars. ⛔ Even if you make it with it, precision laser cutting machine, with which expensive works of art like lithography, engraving on any metal will be made. But his price can be up to 15 million dollars. All of the above but that $100 1 kg iron bar is made of. The above examples prove that the price of something does not depend on what it is made of. Rather, the price depends on how the maximum potential can be used. Thank you! (Taken from Collected English Posters)
