I was going to Kennedy Space Center a few weeks back with a Kansas space camp
from the Kansas Cosmosphere and Space Center
(oh wait, it's not Space Camp...NASA has tried to sue them multiple times for that...it's the Future Astronaut Training Program). I needed a name tag of some sort on my checked bag, but my standard index-card-laminated-with-tape would never stand up to baggage handling. So, I made my own, durable plastic name tags.
Obligatory safety information: Don't cut yourself with scissors, poke yourself with the pointy plastic corners, pinch yourself in the keyring, gouge yourself with the drill, burn yourself while singing the edges, obliterate yourself by jumping in front of a dump truck, or sue me after doing something dumb. If you read all this, kudos to you, because I didn't.
