So several coworkers and myself were in the breakroom this morning and someone opened up the work fridge. When I saw this 2 liter, I immediately asked, 'does anyone know how to keep 2 liter sodas fresh?' No one did! Why have we not cracked this code yet? Do people still buy 2 liter drinks as opposed to cans that do stay fresh and don't go flat? I always thought the key would be to screw the cap as tight as you could so no air would get in and that was your solution. Nope, it's not! Does anyone have the secret? How do you keep a 2 liter drink from going flat?
