10. Human blood – $1,500/gallon
Are you surprised? You shouldn’t be because the cost of blood mainly depends on the blood type. In fact, there are a few blood types which are super rare, making them quite expensive.
And let’s not forget you can’t just keep blood in some plain glass jar. The cost of processing is the real culprit here.
9. Gamma Hydroxybutyric Acid (GHB) – $2,500/gallon
Human body secretes a lot of yucky liquids, but this GHB, which can be found in our nervous system, is also sold on the streets as an illegal drug, and goes by the name “liquid ecstasy”.
So yeah, you’re doing ecstasy right freaking now (or not, I don’t know how GHB works).
8. Black Printer Ink – $2,700/gallon
Okay, there’s a whole global conspiracy here! To make money, these ink companies sell their printers at a low price and earn back their money whenever the consumers want to change the cartridges, which is like once every 500 pages.
For some reason, black ink, in particular, costs a lot more than other colors.
7. Mercury – $3,400/gallon
“But Mercury is a metal. Shouldn’t all metals be technically considered liquid then?” – I can hear you say. And you are right, but Mercury is the only metal to be in liquid form at room temperature.
People used it in medicine, but then after a few thousand deaths, we’ve figured out that it’s not very good for us.
6. Insulin -$9,400-$100,000/gallon
Insulin is a hormone naturally produced by our pancreases, so why is it so expensive? Thing is, people suffering from diabetes often can’t produce enough insulin, that’s where our old friend “chemistry” comes in.
The synthetic insulin is much cheaper (still hella expensive) than its natural brother, that’s why there’s this huge price gap. Well, that and cash-grabbing pharmacies.
4. Horseshoe crab blood – $60,000/gallon
Over 50 years ago scientists discovered that this creature’s unique blue blood is perfect for determining whether a medical product is contaminated or not.
Of course, nobody cares about the Horseshoe Crabs. Humans are way more important, right?
