Laken ISO 70 Aerogel-Insulated Water Bottle
The "Laken ISO 70" water bottle's outside shell is made of aluminum, but its filled—partially, of course—with aerogel
, that wonderfully lightweight and low density material that weighs just three times more than air. It's a great insulator, helping in making a water bottle that's half the weight of a traditional all-metal vacuum thermos.
The Laken ISO 70 aren't cheap, though, at 60 bucks a pop. But in a pinch you could crack one open and catch interstellar dust
