Pok is no user of this forum anymore. He claimed the rights on his pictures and that they have to be removed as he left. So I think there's no chance to get them back.
Videos are only linked here. Since Pok switched them to private on his YouTube channel they cannot be watched here anymore, too.
But it would be a great gain for this article, if you post some pictures and the video of the experiment after it was recreated by you or Mr. Szydlo. :)

Hellow Andrew! Perhaps you don't need to watch the video The description of the experiment ist fairly precise and should be sufficient to repeat the procedure. Google translator should help. :)

Hi Lemmi,

Yes, I read all the descriptions carefully with Google translate but I would still like to watch them. Google translate is not perfect as you know plus I am more of a visual person and images do help. I do have Faraday's diagrams/drawings as well so I think those might help.

Thank you and Aliquis for your encouragement!

As Andrew Szydlo always likes to say 'we must get a result' so we'll practice and try and try. In any case, we might just use solid acetylene instead which is easier to condense using liquid nitrogen. I'm honestly worried about glass tubes blowing up.... Years ago I sealed thick borosilicate glass tubes with dry ice to show liquid CO2 and triple point of carbon dioxide but none survived.

Thanks again,
A

Our ex-user also described a procedure to make glass tubes filled with hypercritical carbon dioxide (see here). Sadly, this description also is without pictures or videos.

May be easier to condense and solidify, but be very careful.

According to the "Encyclopedia of Explosives and Related Items"* Pages 168 until 172 is liquefied and solid acetylene explosive and can be detonated form a spark, blow or detonator. The sensitivity is slight, but it´s better to be careful....because I remember the problem of diazomethane with ground glass joints....

Thank you very much @BJ68 for the info :thumbsup:

I think then we might give this a miss then or try this on a very very small scale...
