''are made of plastic and would melt or ignite if placed over direct heat from a stove'' – no, they wouldn’t; not as long as there is liquid water in it. You can even use a paper-cup to boil water. --[[User:DaB.|DaB.]] ([[User talk:DaB.|talk]]) 17:03, 7 October 2016 (UTC)

: I thought about that too but it depends on the thermal conductivity of the material. Paper cups are thin enough to transmit the flame's heat to the water efficiently; the same is not true of a styrofoam cup. (Another word that is technically still a trademark, by the way.) I suspect a vacuum-cleaner canister would be thick enough and enough of an insulator that it would get damaged.

::Also, some kinds of plastics, while not directly melting, will become "plastics" enough to bend under weight even in temperatures near boiling water. PET bottles will not survive boiling water, for example. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 15:21, 9 October 2016 (UTC)
 
  
 
Another reason why the coffee will be very expensive: if you throw a package of beans on the ground, you need many, many, many beans, as there is not enough surface on the beans to make the water brown and give the water any taste. With ground coffee you can get several cans out of one package, the method illustrated here needs at least one package per try. --[[User:Anonymous guest]] [[Special:Contributions/141.101.104.29|141.101.104.29]] 20:19, 7 October 2016 (UTC)
