In edit forgot to mention entry in ATK at $49.33 during that hickuo period on I-hub.
The earth weight actually increases a little as meteorite bombardment compensate for the slow loss of atmospheric gases. The three containers (if indeed perfectly sealed which an impossibility) will have the same weight, though in practice, diffusion will cause the warm one to lose weight faster than the other two. Both result from the law od conservation of matter.
In the meanwhile got GENZ at $30.16 and AMGN at $51.82. Not waiting on AGM print of $24, out here between $24.30 and $24.32, the decline is too fast and a print of $24 is imminent.
