I was planning to do this at some point but it looks like you beat me! :p

Why is the freeze dryer so sensitive to moisture? I would have expected there would be much more water in its intended application than in your beaker...

I'm supposed to change the oil after every run; I'm not that rich! lol :)

I like the ice spike. Any ideas why that occurred that way? Can you do it again? Until I got my -105 C cold trap freezer, I used to use dry ice and denatured alcohol with a vacuum beaker submerged in it to keep stuff out of my vacuum pump oil. Two stages are better than one for this. It makes a huge difference in how low your vacuum goes if there is water in your oil.

I just want to point out that you drinking some of the water proves nothing because we remember that other video.

Cody -- I was recently reminded of "cold welding" and did a bit of research. From what I can tell it's actually not as easy to perform as initially assumed. That said, if you get the chance look into it. I believe the hardest part would be ensuring no oxide layers and actually bringing the metals together while inside a vacuum. Perhaps suspending both pieces of metal and holding them apart using string and magnets --allowing you to release it by removing an exterior magnet. Hope you take a gander :)

Honestly I think it would be easier to do in an atmosphere of argon but I'll look into it.

I imagine removing the oxides would also be easier in argon and from what I've read gold would be most suitable. Either way, I think it would be very interesting if you could swing it. Thanks for looking into it.
