paper cookware lighter than titanium?

This is one of those neat tricks that we just wow young Boy Scouts with! They're always amazed to see that you really can do this.

The cup MUST be filled with water (at least two-thirds full). It works because the water prevents the paper cup from getting too hot. Water boils at 212*F and as long as there's water in the cup, the cut won't get hotter than than. Paper burns at 451*F — so there's a large safety factor.

If the flames get too high and start contacting the top edge of the cup (the portion without direct contact with water), its possible to burn the cup from the top.

Sam Sam,
We've done this several times. A 32 oz paper cup weighs about 20 grams, a ~ 31 oz titanium pot (without top) weighs about 90 grams.
Rumor has it the titanium pot will last longer ;)
You can easily boil water, make soup, boil an egg, or make a baggie omlet. As mentioned above, you have to keep water to a high level in the cup.

The type of cup can make a difference, avoid waxed cups if you can.

I wouldn't recommend this without a backup plan. Try at your own risk, your mileage may vary, never put hot coffee between your legs while driving, close cover before striking.

20 grams sounds heavy :) A beer can pot is just a couple grams more… and more durable. Neat trick tho'. I had not idea! That's pretty wild.
