Death by Caffeine - How much can you handle?

I have been having fun playing around with a site today.  It is called Death by Caffeine and it is fun.  Basically, you can select almost all drinks and see how much you have to drink to overdose on Caffeine.  Take the Link over to Death by Caffeine.

There is also a death by food type site there has well.  It is called Death by Penguin Mints.
