"I can remember when the first pulsars were discovered. I was able to go and sit down and listen to graduate students talking about what their theories, to explain what pulsars really were."
- Vernor Vinge

Water Bulb  
  A zero-gee dispenser of liquids.  

This particular device was used on a Moon shuttle.

I held up my bulb of water and my ration box. The seal had clearly been tampered with on both containers, and visibly there was water missing.
From The Space Merchants, by Frederik Pohl (w/CM Kornbluth).
Published by St. Martin's Press in 1952

Compare to the drinking bulb from Larry Niven's 1966 short story The Warriors (although most readers probably remember it from his 1971 novel Ringworld). In Niven's Known Space, drinking bulbs were used by everyone, even on planets.
