Did u know that Steve (main character in minecraft) is extremly strong. So in real life the heaviest item in minecraft would be a golden block which steve can carry 64 per slot, u following me? So there are i think 36 slots in steves inventory. And when we skip all the mathematics behind it the weight he can carry is equal to 6 eiffel towers. There is a whole youtube video that covers it pretty well u get me...
