 The bubbles are supposed to make them airier and fluffier. A full 12-ounce can is enough for 72 eggs. What are you going to do after you do that, though? They do say, though, you've got to use plain seltzer water because if you use something like LaCroix or those, and I just think that those taste horrible. I know my kids love them. They say your eggs will taste a little weird, so don't use White Claw either. Okay.
