Sitting here with my roommate, and we’ve come up with a question: What is the cheapest commodity by weight?
In other words, we’ve got a one ton scale and we want to test it.
As our test-facility is in the middle of the Ghobi Desert, we won’t be able to collect water to put on the scale, and sadly, the resale value for sand is practically non-existant. With our high-speed internet access, though, we are willing to import to our laboratory that one special item which we can find most cheaply.
So, what commodity can we purchase most cheaply?
