Ann,

Unfortunatly for your wily plan, the Jerusalem Artichoke has quite the opposite effect. It only results in a previously unheard of high noise level. Simular to a 100.000 ton ships foghorn.

If the Victoria Falls is known locally in Zimbabwe as "The Smoke that thunders", the J.A. would be known as "The Root that thunders"...

Like I said, wear hearing protection.
