Loud Whistle! (MakeItLoud V29 improved)

This is a modified version of the MakeItLoud V29 Whistle that puts out 118+db.

I made the design a lot thinner and a little smaller so it can be more portable.
I also added a second hole that works very well on a smaller keychain.

The original design didn't sound very well if you did not blow very hard, but this one works pretty well even if you blow more slowly and less loud, but it still gets REALLY loud if you blow hard.

I really liked the original whistle, but this saves me time, plastic, and space!
