One day when I was thinking, I had a great thought: What happens when you put Bose-Einstein condensate into room temperature or into a very hot place very quickly? So usually it is made by freezing liquid helium to ultimately low temperatures (like a fraction above absolute zero (0 Kelvin or -273 degrees Celsius)). Normally if you freeze something and then heat it, it goes back to its original form, e.g. steam –> water –> ice –> water –> steam. But Bose-Einstein condensate would probably change permanently when the helium atoms turn into waves.
Mum said that it is the same as with eggs, once you boil an egg then even when it gets to room temperature it stays a solid. But eggs are not from a single similar molecule (water is just H2O and Bose Einstein condensate would have been helium). Eggs are surprisingly complex. And so is Bose-Einstein condensate but in a different way. I couldn’t find anything on the internet about this idea; surely somebody has done this experiment already.
