Using readily available household components, what combination of
items could make a close approximation to blood? In other words, if
you wanted to make a quantity of artificial blood for testing in an
ocean environment, what combination of readily available items could
you put together to get close enough to blood for a rough test? (think
sharks) |

Close approximation in what way-- Color? Consistancy? Smell?
What kind of test? --Your question is confusing.
Are there going to be sharks present?
If so, no amount of FAKE blood (red stuff) will affect them, but a
tiny bit of real blood can be detected by sharks over great distances.

Just in case you just want simple fake blood, here's a page that has a
recipe for realistic fake blood using household products.
How to Make Fake Blood
http://www.dainter.com/infocus/fakeblood.htm
If this, and a couple more sites with different recipes is what you're
looking for, let me know...
Adding for researchers to "think sharks" made your request
confusing... did you mean thunk "fake sharks?"

I am assuming that blood cannot be artificially produced (if it could
there would no longer be a need for blood banks, etc.), but since
blood has certain physical properties (protein? salt?), I was trying
to ascertain if there is any way to approximate blood and its "smell"
in the water using common items.

So appearance and consistancy don't matter. You're looking for a
substance that you can make out of household or easily obtained items
that will attract real sharks in the same way and frequency as real
blood... Do I have that right?
Assuming that is correct, I'll see what I can find, no guarantee. I'm
leaving the question unlocked, which means that any researcher can
still help...

Not much luck, sorry. Here's what I found, which is interesting but
not what you're looking for. I'm curious though, if you want to
attract sharks, why not chum for them like the pros? Seems you're
trying to find or invent something when there is already methods in
place to lure sharks.
What attracts sharks?

Urine trouble

..."Q: Surfers' lore says that you should never urinate inside your
wet suit as it is believed that the urine will attract sharks.
However, I would expect the opposite to be true. Shark blood has a
very high urea content and it is also known to be a potent shark
repellent. So why is human urine not considered so?
A: All fish, including sharks, contain a high concentration of urea in
their blood which is responsible for the characteristic ammoniacal
fishy smell. A shark's sense of smell is good ?they can detect
concentrations of approximately 1 part in a million ?as is their
ability to detect vibration. Their eyesight is poor ?but since they
haven't needed to evolve greatly in the last 250 million years we can
presume sharks are well adapted to their environmental niche.
I would imagine urea released in the water would confuse the shark's
sense of smell rather than actually repel it. However, human urine
would contain hormones that are similar to organic chemicals that
sharks use to locate their prey. Therefore it would be these human
hormones that the shark would detect and home in on..."

The application I intend to use this information for is not actually
for sharks. But I am trying to find out what is similar enough to
blood to do a similar job in a similar environment. Chumming doesn't
help in this case, unfortunately. Thanks for your advice, however.
