Friends returned from a Florida vacation with souvenirs from the Kennedy Space Center, including a set of three shot glasses (made of space-age plastic) screen printed with colorful images and logos. Again, we, the tax-paying consumer, reap the benefits or NASA research. I'm sure their purpose is to toast successful launches and landings, for use by tax-paying consumer-spectators only; not intended for use in zero gravity. Although I doubt there is an equivalent keepsake for sale at the Russian equivalent of the Kennedy Space Center, if there is a gift shop there and if they do sell vodka jiggers, I hope some international traveler friend brings us a set of those, too.
