What there is no water in that bottle!!It is no different to putting the foil directly onto the pen part, if all areas are sealed it works the same and no need for water!!

^Failed GCSE PhysicsIt makes no difference if there's water or not.

Okay let me better explain myself...Suppose we apply negative pressure to the biro mouthpiece as illustrated above (assuming the bottle is waterless). Both the bottle and the bowl are significantly greater volume than the draught hole resulting in a longer, but weaker burn; you would need to suck a lot to get a little. You've created, ironically, a bottleneck.
Reverse the setup so the bowl is mounted on the biro and the bottle opening is the mouthpiece. Now you only need to suck a little to get a lot. 1 standard toke results in a lungful, rather than a gnat's fart; there's a higher delta-p at the bowl and a much faster transfer rate from chamber to mouth to lungs.

Worse than useless with water.Still less advantageous than doing away with the bottle and the pen (see below).

I should add that a perfect seal between the 3 pipe components wouldn't exist in reality.A better design would probably do away with the plastic parts completely (except for using the biro as a mould for the foil, possibly), but I digress.
