Watch: How to Make a Fog Horn from PVC and a Funnel

So you need a noise-maker to alert the compound of impending danger, but it’s already hit the fan in a big-picture way and you don’t want to leave your comrades for a trip to Wal-Mart. What to do?

If you’re this guy, you put together some PVC pipe fittings with a piece of Ziploc bag and a funnel, and create a loud air horn that can be heard for quite a ways!

Check out the progression of sounds from high pitch to low just by adding a funnel, and one heck of a weird sound after he adds a long length of pipe in place of the funnel.

Pretty cool.
