How To Make A Fog Horn - Easy PVC Design

How to make a simple Air Horn. These horns are LOUD! They can be scaled up as I show in the video, but be aware that the bigger you make them the more air they will take to function. Get your free audio book from Audible here: http://adbl.co/17ujzYW (I finished The Martian, highly recommended)

Parts used for this project (small version):

1"x 1"x 1/2" T Fitting
1" x 1/2" Adapter
1" Plug
6" x 1/2" PVC Pipe
Freezer Bag
Long Funnel (found at auto parts stores)

Parts for large horn:

2"x 2"x 2" T Fitting
2"x 1" Adapter
2" Plug
6" x 1" PVC Pipe
1" Coupling
Freezer Bag
Large Funnel
2"x 1" Reducer
1"x 1/2" Reducer

Both horns are operated using a large manual air pump in the video, though they can also function using compressed air or simply by blowing into the inlet with lung power. #NightHawkInLight
