How much toast can a lightning bolt make?
How many pieces of toast can you make with a lightning bolt?
We're nearly at the end of the show, so I should give you the answer to our toast question. It's about 100,000, as Ed suggested, because basically, there's 10 billion joules of energy in a lightning bolt and it takes about 100,000 joules to bake a slice of toast.
So, if you divide 10 billion which is 10 to the power of 10 by 10 to the 5, which is 100,000, you get 10 to the power of 5, or 100,000...
