I recently moved to a place that doesn't allow brewing equipment to be imported (But it is legal to brew... don't ask me). I've built a lot of my stuff, but I have a question about airlocks. I've come up with two ideas.
1) Simply running some tubing into a cup of sanitized water.
The problem I have with this is that I am worried about the tube slipping out or the water evaporating.
2) Curling some tubing into circles and adding sanatized water into the bottom of the tubing.
I can accomplish this one easily with some thicker tubing and zip ties, but I am worried that is won't function as well as number 1.
I want to design one that I can use many times over. Does anyone have experience with homemade airlocks or feedback on the two designs.
