Making a DIY Fog Horn is a fun and easy project. In the video below, we’re checking out a simple PVC design that requires 4 PVC parts, a plastic freeze bag and of course, air supply to power the horn.
This particular design can easily be scaled up to larger sizes by using bigger PVC parts. If you want to get a deeper tone, then simple extend the barren with a funnel. The only thing you need to be careful about is the precision of your action. But, if you closely follow everything explain in the video, then you shouldn’t experience any problems.
