The reason for headspace in the packaging is exactly as you said. Liquid will expand and contract with heat and cold the same as gas and air. However, hydraulics are used for force in machinery because a liquid will not compress to a smaller volume as a consequence of pressure but gas and air will. By adding pressure to a gas, you can fit more of it in a finite space. If you add liquid to a finite space that exceeds the volume of the space compression results in force. That force will exploit the least resistance and exit through it. This is why brakes on a car have to be purged of air or gas. If there was air in the system, the brake pedal depression would compress the air and not translate to optimal force for applying the hydraulic piston in the slave cylinder, reducing their efficacy. Great topic Steven.
Your beer looks delicious! My understanding is that those cans can handle a lot of pressure. So glad you gave it a try. We've done that with beer that won't fit in the keg. Cheers!
I always wanted to try to can condition some beers I’ve made, but my concern is oxidation. I remember Brian at short circuit can condition some of his brown ale I do believe, and he thought one was oxidized. Plus I wouldn’t know how many of those sugar cubes to put into the can. I just figured I would go with one and fill it or the crease at the top of the can to have some headspace.

I've been doing a gyle ..saving about 1 pint of the original wort, throw it in the freezer, and then use that (reboil first to sanitize) to carbonate.
You CAN do it! 😂
I see what you did there
