@thebrainmaze: An animated comparison of some of the world's most expensive materials (per kg), showing how much money you'd need to buy them. It covers everything from cheaper materials like iron ore and granite, to expensive ones like silver and ivory, luxury items like diamonds, rubies, and sapphires, and ultra-rare substances like Californium, Platinum 190, and antimatter. Keep in mind, the figures are rough estimates based on available data and may not reflect current market prices. Prices can fluctuate and do not account for inflation. #comparison #animation #fyp #foryou #viral
