An idea I had, bag filler machine

So with so many vapes out there why doesnt someone make an attachment that uses a variable fan that has a silicone tube (so you can use it universally with many different vapes) that connects to a gong bag? I would think the cost to make something like this wouldnt be much since it doesnt take much power to fill a bag. I know I would buy it just for the party occasions or showing off; but would likely find its use a nice thing to change it up with even if im vaping alone.
