great work here
@ Harvey
please could you repost a better pix of your device once completely iced. The previous pix do not clearly show the depression in the center. I know that it is difficult to show the variation of form on ice, but try, it would be very helpfull.
and please can you make a new video with the cam fixed above the device without moving. So perhaps we could learn to see the subtility that David try to teach us. Thank's
@ Jetijs
Did you already made some test ?
As for me i go on in icing test. So far it is the only mean i have found to see something in this radiation waves. But there is no doubt that the assymetry is there. This morning i asked my daughter to let her hands on a completely iced pmh. And estonishly she sayd that the "heat spot was where there was less thickness of ice ?? " So a question does the pmh Compress the water icing process on one side and depress on the other ??
And the question is why ? Any idea ?
Have some more icing this night. We will see tomorrow
Good luck at all
Laurent
, but I would suggest to freeze your PMH's with the N pole prong East and S pole prong West...if possible.
