I have discovered virtual water! And it has virtual weight, too.

I am still laughing -- you made my day!
We all live in a virtual submarine...

Bah!

Well, you made me do it. I got my hands wet, doing a simple experiment that led me to an interesting conclusion and discovery.

Strange isnt it?  ;]   Now, if you second, displacement, glass had no weight, and was affixed to the first cup, just as it is in the vid, what would we see on the scale?

Mind boggling

But that is just a magic trick M.  TK is showing something real. ;]

Well not so mind boggling. The weight of the stand with the glass holder is applied to the scale by displacing the water.  But displacing the water with a second empty glass fixed to the first glass, should only add the weight of the second empty glass. Right?

Like if you set it up the way you have with the stand, and have a way to bond the 2 glasses together while held in place and then removed the stand......

One might think that if the glasses were bonded together and the stand removed that the scale might show no difference, stand or no stand.

But I can see that even at the time of bonding of the glasses, that the stand is applying pressure to the scale, even if it is not the weight of the stand that is displacing the water after the glasses are bonded. After bonding, the weight of the stand is applied to the scale directly through the glass and the water is just additional weight.


Ah, so this is the why of the separate free floating chambers in the risers. Im getting an inkling of what is going on here.  Ill see what I can make of it.

Thanks for the vid T. ;]
