Rice pulling is shown by Iridium metal which comes due to radioactivity.Copper utensils are not able to show rice pulling as there is no chemisry which can change utensil of copper into iridium.People fool others to make money so I advise everyone not to engage in this activity as it lead to wastage of time and money Videos of Rp are made artificially with the help of pulling them with very thin wires which cannot be seen. Iridium is found in remote areas in traces and these areas are out of reach of ordinary man due to radioactive emissions present in that area. Make deals of items without any functios as these are created artificially.If my post is helpful to anybody plz reply. Stay safe. Ashu(Saharanpur).
