Why sip from a boring flask when you can ignite conversation with this super unique Hydrazine Barrel Flask—a cheeky tribute to the dangerously volatile (and completely undrinkable) propellant that powers actual spacecraft? Mark Watney approved as long as you have an iridium catalyst.

Shaped like a mini fuel drum and stamped with all the actual NASA required barrel markings for methylhydrazine—and hazard symbols for dramatic effect, it’s the perfect mix of nerdy, nostalgic, and just a little unwise-looking.

• 25 ounces of capacity! According to Alexa, that's close to a full 750ml bottle,

• Stainless steel with matte “hazard barrel” finish

• Leak-proof screw cap and industrial-style ridges
  

• Not actually dangerous... unless overfilled with confidence

Quirky. Questionable. Quintessentially space-nerd.

Because some fuels are flammable—others are just fun.
