Is it really possible for a liquid to stay afloat a gas (vapor)?

I have a book at home called [Chemical Thermodynamics for Process Simulation](https://www.wiley.com/en-us/Chemical+Thermodynamics+for+Process+Simulation,+2nd,+Completely+Revised+and+Enlarged+Edition-p-9783527343256) (I have the first edition) and at the very beginning of chapter 2 of the book one may read the following:


[![CO2-water system at high pressure](https://i.stack.imgur.com/sK6nN.jpg)](https://i.stack.imgur.com/sK6nN.jpg)


No reference is given. I have never found anything about it so far and I am curious to know whether this statement is true.




Yes! Here's a video of Cody floating NaK (liquid) or ethanol/water (liquid) on compressed xenon (gas):
