Question about making a DIY bubble counter

I just made a simple DIY glass jar bubble counter and have a few questions. I sealed up around where the CO2 lines go in and out (both sides) of the lid. I hear people talking about how air leaks are common with these things. Do I need to add caulking to the lid to get a good seal, or will my pickle jar lid seal itself?

depends on how big you make the holes, but a little silicone wont hurt.

So i've had the thing running for about an hour now. I have about 1 bubble every 4 seconds (I just changed my sugar/water/yeast solution). I'm not seeing anything come through the chopstick. I had it straight line to the chopstick this AM, so I know it's working. How long will it take to build up pressure again you think?

I put silicone around all the seals, including under the rim of the lid to the jar.

I'm leaving for the weekend in a few hours... probably not the best time to start a new project, but that's just how I generally roll.

i would think it would tank an hour or less to build up pressure, you may have a leak somewheres.

Damn... I even dunked the whole setup in a water bin to see if I could find the leak, but no bubbles.

Alright so here's my stupidity... Hopefully I'm saving someone else from wasting time, but make sure you wait for your silicone to cure fully.

Please save all laughter till after the show.

I'm only laughing because it's something I'd do.

Easiest way to make a bubble counter is with a water bottle. Just drill holes in the cap that are a little small for the tubing to fit, then cut the tubing diagnally at the tip and pull it through with pliers. This way, you dont need glue or anything. The holes squeeze the tube enough to make it air tight
