You guys are either going to laugh at me, because you've been doing this forever, or you may think I'm a little loose.
In any event, I have a Frankford Arsenal vibrator (cheapie). Works great. It has a clear plastic lid, so when the vibrating occurs, you can easily see what's going on. The other day, I touched the lid during vibrating, and noticed a very real change in the vibration pattern. It went way faster. So, being the knucklehead I am, I tried taking the lid off and ran it that way.. SUPER OVERDRIVE !!!! I'll bet the speed picked up by three times.
Now, my corn cob is about 2 inches from the top of my bowl, but the little pieces don't even spill out all over, which I thought they would. I can cut my vibrating time in almost half. Certainly, a small matter - but I was impressed. I've also noticed that the majority of the vibrating case cleaners have a colored lid, so we can't see what's going on. Anyway, anybody else ever try this ??? enjoy Mike
