Antigravity Fluid Tube - Glass Sealed Xenon Supercritical Fluid

Very cool demo. It will grab people’s attention with how bizarre it is to see liquid falling upward. It’s a great conversation piece. You can also cool it below the critical point (about 60F) and the xenon bubble will start separating into liquid and gas, leaving the blue alcohol in the middle. The folks at Haloplasma were also very friendly and helpful with answering some questions I had. I’ll definitely be looking into more from them!

Beautiful!!
