Here’s a fun little mystery for you guys. How can taking away 4 oz of coffee produce more cups of coffee? We’ve been thinking about it ever since Blueprint for Financial Prosperity sent us this photo the other day, and we just can’t figure it out. Could it be magic? Some strange new property of the Grocery Shrink Ray?
I bought a can of Folgers coffee two days ago from Costco. When I compared it to my last can, also from Costco, I saw that the new one had 4 oz less of ground coffee. Ok, no big deal, but then I saw that the small can claimed to make more coffee than the larger can. This is the first time I’ve seen a company shrink their product but claim you get more. It’s not a matter of coffee potency either, the preparation instructions are the same.
Now we’re not math geniuses or anything here, so please do let us know if we’re missing something or messed this up but, the preparation instructions are in tablespoons (volume) and the product is sold by weight… but the ingredients say that both cans contain 100% pure coffee. Has the density of coffee changed lately?
Hmm, let’s see. ?=m/V, and 1 tablespoon is 15 cm³… 360 6 oz cups…
By our calculations, the old density of Folgers coffee was .272 g/cm³ and the new density is .238 g/cm³. Did you guys get the same thing?
The shrink ray is getting more complicated all the time.
