Smoking underwater? That just raises further questions!
This strange post, featured on imgur, on Minnesota State Law strictly prohibiting underwater smoking is begging the question: how does one go about smoking underwater in the first place? And why is it so rampant that the Minnesota legislature actually had to bother passing a law to ban it?
Silly as that is, Vermont has got Minnesota trumped. It is against state law in Vermont to whistle underwater.
A whistle for underwater whisteling sounds rahter like a physical challenge, to develop a whistle that may be operated by a water jet...
Alternatively. just connect a pressure hose from a diver's air tank to a whistle in a diving bell... this should be heared even outside the water...
The main question remaining would be how to get the local Sherrif to give you a fine ticket for this crime, (and how much it would cost).
Sounds as fun as getting registered as monkey feeder at teh Tōshō-gū shrine in Nikkō, Japan...
