What's five times hotter than the sun and capable of sending a DeLorean back to the future? Yep, the answer is a bolt of lightning, which can reach temperatures of roughly 30,000 kelvins (53,540 degrees Fahrenheit). The sun, on the other hand, is eclipsed in this case - its surface temperature is just 6,000 kelvins (10,340 degrees Fahrenheit).
Lightning is over 40,000 degrees Fahrenheit. A bolt of lightning heats the air along its path causing it to expand rapidly. Thunder is the sound caused by the rapidly expanding atmosphere. The purpose of this experiment is to watch lightning and hear thunder to give you clues about how far away you are from a storm. One thunderstorm. A stop watch (or the ability to say one-Mississippi) 2. For every 5 seconds the storm is one mile away.
