Dorky Poll: Physics Scavenger Hunt!

In the same basic spirit as the previous post, but with a physical science slant:

What items should be on the list for a scavenger hunt through an academic physics department?

The idea here is to keep a big group of grad students occupied and entertained for an afternoon by having them find items characteristic of academic physics research, such as:

  • One working piece of apparatus powered by vacuum tubes
  • One obviously broken piece of apparatus being kept “for spare parts”
  • One obviously broken piece of apparatus being kept for no apparent reason
  • One piece of computer software that’s at least two versions out of date because nobody wants to deal with upgrading it
  • One piece of computer hardware that’s at least two versions out of date because it works, and nobody wants to deal with replacing it
  • One faculty member sleeping through a seminar talk

What else needs to be on the list?
