Amusing little caffeine factoid engine which spits out how much of your favorite caffeinated beverage would kill you. First you select your beverage from the drop down menu, enter your weight, and click the appropriate ‘Kill Me’ button. According to Energy Fiend, it would take 351.29 cans of Coca-Cola or 149.3 cans of Red Bull to set me free of all my troubles.

There is a science behind the “Death by Caffeine Calculator”:

The lethal dose is based on the LD_50 for oral ingestion of caffeine, and a lot of studies report different numbers. The one I’m using is about 150mg/kg. If you were to get caffeine injected into your bloodstream, as little as 2 grams can kill a grown adult. LD_50 is a medical term to indicate the dose that kills 50% of the test subjects. I’m not sure how they figured it out for people…

The number of cans/bottles/etc the calculator gives you assumes you can drink it all immediately, or one-after-another. Physical limitations mean that you probably can’t drink enough of anything to kill you, but you can certainly start freaking out, hallucinating, go into shock or seizure, all sorts of cool things.

What’s your poison?
