Given the explanation above, it would need to be a funnel that is cheaper than paint. If the analysis above Is accurate (I can’t vouch for it either way) then it’s hard to imagine a material strong enough at such a low price point. It’s possible too that the proposed mechanism is related to electrostatic charge in which case funnelling would probably interfere.
