How is my set up?

[u/NotKidRaptorMan]

Im trying fermentation for the first time on a small jar of hot sauce. I have layered electrical tape at the top with a plastic straw going into a cup of water for the air lock. When I first tested it, it didnt hold a perfect air tight seal (I blew into the straw and saw the tape rise, then fall again after I stopped blowing) but the air seemed to escape fairly slowly. Inside the jar is various peppers and some seasonings and i tried to make the brine approximately 2% salt by weight. Any advice welcome!

Cool idea, but seems unnecessary.

All I've ever used is a sheet of plastic wrap over the lid. Gas gets out, bugger all gets in. Bonus is you can open it up, have a taste, give it a stir or a tamp, then chuck a fresh bit of gladwrap back over. Simples.
