You can make your own almost-Coke... OpenCola, the open-source cola. https://en.wikipedia.org/wiki/OpenCola_(drink)

our local indie cinema produces its own cola using this recipe, it's very good, so good that they actually produce and sell it in bulk.

Yes, but the pressure is the same on all parts of the can. Ok, almost the same, still.

Maybe because of the parts that have been cut to make it easy to open?

I wish Coca Cola would make a acid free version of coke. The Phosphoric Acid adds a slight tang to the drink, but in exchange absolutely destroys your teeth over years of consumption. For regular drinkers like myself I'd happily pay a small premium to buy the "acid free" version of the drink. The sugar still does damage but with both the acid AND sugar it is like a double whammy of "badness" (acid which destroys your…

I'm no chemist, but couldn't you just add a base to neutralize the phosphoric acid (e.g. calcium carbonate)?

It would be interesting to see how the cocaine supply line works. I imagine they'd need armored vehicles and a lot of security for the entire trip from NJ to MO.

When a shipment arrives in the U.S., a high-security convoy of trucks ferries the leaves from the docks of Manhattan to Maywood, where it is greeted by a rifle-toting guard. After production, armored cars leave the building loaded with barrels of high-quality cocaine.

Try drinking water and eating fruit when you feel the urge to have a soft drink. Maybe you do already. It worked really well for me.

In my country Coke is used by plumbers to unblock drains and pipes. Just knowing that has always discouraged me from drinking it.

Nope, the pressure from the carbon dioxide pushes equally against all sides of the can. If anything the pressure at the top is slightly lower than at the bottom, at least if the can is standing, because of the weight of the coke pushing against the bottom.
