Keep a couple of blank CDs handy.

They're extremely reflective and the hole works really well for aiming.

Actually, Civil Air Patrol and the local search and rescue group
tested this, and they really are not effective for signaling.
If it is all you have, use it.

Much better: USAF 4"x6" or 5"x7" glass signal mirror, with sighting
hole.
