The Blog of a madman (the good kind). This guy is always throwing parties for his little scientific experiments: 'How much is Inside?' is a favorite recurring experiment:

He tested how much is inside a Sharpie pen by seeing how many CDs he could write labels for. After 2 months and almost 1000 CDs, he finally ran out of ink. It is this same exhaustive effort you will find in 'How Much Is Inside':

A bottle of mustard
A Keg of beer
Dust off
Print cartridges
Batteries
Lipstick
And more!
