i find powder in the bottle.
powder i may get to deconstruct landmines.
I think that the storage of the powder in the bottle a much more convenient than in the form of powder is poured into a backpack or some other pockets of clothing.
Can such a way to save space in your inventory, as an empty bottle and full bottle take inventory the same volume - respectively - more efficient to keep the bottle is not empty but filled with something. do anything - pour into them from paper bags flour or cereal, freeing up space in your inventory.
will now be a little blackmail 
Incidentally emerges another dimension. I am here at a forum saw a fight between those who argue that the fluid can be collected and those who argue that it is impossible to collect the liquid. as well as you, claiming that the liquid can not collect such incident - powder and flour from the floor you somehow gather without losing anything.
It may then be done non-rising and powder and other particulate matter. flour, powder, cereals. No I’m not saying that if the solid material is poured a handful of his quite impossible to collect. I say that it is impossible to collect without loss. and the more the greater the loss to pour.
let’s say if we are emptying flour heap on the floor capacity of let’s say 100 units that raise it off the floor, we can not say more than … let us say… 90 units for the rest of the meal will be soiled.
so - could be worth permit those who want to raise the liquid from the floor with a mop - still do it?
Or at least make a half-hearted decision to allow to take into account the liquid on the floor in a recipe? 
to explain the unexplainable (how to raise the liquid from the floor) - it is possible to refer to the example of David Blaine walked past and gave us a street magic and gave us local time paradox, when the liquid was poured and we do not change your mind :)) and all hush-hush
ok i’m just kidding 
but nevertheless - in every joke there is only a fraction jokes.
I say that it is necessary to introduce a mechanism for the loss of bulk materials, caused by their contact with the dirt of floor.
and - to make sure that it was possible to fill particulate in the container independently and not only by discharging.
