Your Burnt Toast Can Be Made Into Diamonds
Given the right circumstances, any type of carbon can be made into diamonds. To take a severely burnt piece of toast and turn it into a diamond, it must be ground down and squeezed into a mold. From there, it is taken to a special machine that can apply pressure to it that is 60,000 times greater than our atmosphere. The burnt toast will then naturally turn into diamond. Before you start thinking about making your own sparkling diamond jewelry from smoldering toast, know this: two pieces of ground-up burnt toast will produce a microscopic diamond, invisible to the human eye. Magnifying the diamond 10,000 times will make it visible to you.
