What? Rigged! But it is a you tube video...gospel.:angel:

We do not need no stinking education, math, and science to cloud up its validity, I saw it on the internet....:D

Earlier you said:

“I feel a little bad like I'm teasing a kitten”

Don’t, he deserves it IMO.

Never said we need no math, education or science.

I personally do not like YouTube, but its a real world example of a pseudo controlled test. something that puts our math to the nature of reality. Have you not seen prototypes and real world experiments to prove theory?

could it be rigged? Of Course. But I doubt it. someone try it here with a Rubbermaid container.

Tease away, you just prove my point :thumbsup:

i haven't read all of the posts but just to through a wrench in, lobster aquariums are probably salt water

I think they are.

But is the equipment such that the water could be energized? Again, think of a 3 phase pole pump motor. What makes it so special that it can't energize the water?

FWIW, Voltage gradients in salt water as less than that of fresh water.

likely more imo
since Z is lower current will follow a shorter more direct path
gradient = v/L with v being the same in all cases
so gradient higher?

but I need to think about it

lower

think of tap water compared to a copper wire

salt water is more conductive(like the copper wire)

talking voltage gradients here

saltwater is safer
 
From the FWIW department...

Many years ago when dinosaurs walked the earth I was in a fraternity in a major institution of higher learning. There was an annual party that all the "Greeks" participated in called South Seas Island Weekend. All the frat houses and their grounds were elaborately decorated, and a common feature was an artificial body of water created by putting out bales of hay for the perimeter, lining the bottom with sheets of Visqueen (plastic), and filling them with water.

During the construction phase at the frat house next door to ours someone had left a circular saw (the old style with a metal body and no ground pin) lying on one of the hay bales, still plugged in, after the "lake" was filled. A guy standing knee deep in the water walked over and picked up the saw. He died at the scene.

gotta flush them once a week
fill sink with hot water and some baking soda
pull drain plug
turn disposal on until sink is drained

One piece of advice the plumber gave me was to not put eggshells in the garbage disposer, especially if your house is (like mine is) set back a ways from the street. They tend to settle out in the pipes and cause blockages. It makes sense since eggshells are essentially limestone.

Yeah I figured. You brought a knife to a gun fight. Bad idea.



I know what is being discussed.

Guns can run out of ammunition though;)

I think the bigger problem is grease being poured down drain, then increased amount of solids from the disposer to get hung up in the grease. Eggshells are abrasive if you get them to flow may actually do some cleaning along the way.

I think this shows you don't know or are intentionally getting it wrong just to prove me as wrong.


Take a 1 foot piece of #14 copper and a 1 foot piece of #14 nichrome wire. Apply voltage, any kind, and then with a volt meter measure any 1 inch section. The voltage reading will be higher on the higher Z wire, lower on the lower Z wire.
