Here's a brief overview of our current setup (for a school project). We have a CO2 tank with regulator connected to 6 2-liter bottles. Currently we have drilled two holes in the top of the 2-liter caps, one for air in, and another for liquid out. We are controlling the flow out by electric solenoid. However, the problem that we've ran into is that we can't securely attach the tubes into the caps. We have tried silicone (aquarium sealant) as well as super glue and caulking (desperation attempt), but nothing is really working in a reliable fashion.
Does anyone have any suggestions/ideas that would make this process much easier for us? We were thinking in getting rubber stoppers from chemistry application (that have 2 holes in them) but the problem is we have 2 different sized tubes and the holes in these stoppers are normally very small.
Sorry if this is in the wrong place or if this is a question that has been answered; I've been searching everywhere and have yet to find a solution yet. Thanks.
