Eggshell Calcium Coke
-
You can put eggshells into coke (any acidic drink), it will dissolve and release both Calcium and CO2 into it. If you dissolve an entire egg shell that shifts the Phosphor Calcium ratio from 1:0 to 1:10, far more calcium than phosphor making Coke genuinely peaty.

Thought for a second you wanted to sniff the eggshell powder like coke (cocaine) when I read the title.
Does it dissolve well? I tried to make my own eggshell powder a few years ago, but it dissolved pretty badly in coffee. I guess it wasn't fine enough.

@Luke It dissolves very slowly, but it doesn't matter much because you can just add it to the bottle and leave it in the fridge for later. The eggshells also firmly stay at the bottom of the bottle so there is not really any harm from drinking from it earlier either.
Grinding the egg shells is not necessary.

OK PSA because of math. An egg shell is about 2.5g of Calciumcarbonate. Calciumcarbonate is about 30% Calcium. So 1 egg shell is about 800mg of Calcium. This goes into megadosing territory and you might have calcium toxicity.
1/10th is 80mg calcium, enough for the optimal 1:2 phosphor:calcium ratio.
So put 1/10th of an egg shell into your coke.
This is a purely chemical reaction due to the acidity of the coke. Grinding, mixing, etc., has no effect. A whole egg shell takes about two days to dissolve, but 1/10 should just be a few hours.
