How many planetarium people does it take to change a light bulb?
If we’re talking about the bulbs in the projectors that run Morehead’s planetarium shows, the answer is 3:
- 1 person to crawl into tiny spaces behind the walls of the planetarium theater and crouch for minutes at a time while dealing with hard-to-reach screws and bolts.
- A 2nd person to keep parts of the projector from falling onto the 1st person’s head.
- A 3rd person to ferry tools back and forth and to entertain the first two people by attempting (and completely failing) to come up with good light bulb jokes.
3 is also the number of hours it takes to change the four bulbs in the two projectors.
It takes 3 people to change the bulbs and then many thousands of visitors to enjoy the results.
