So we get onto the instructable itself.
Now, before I go any further, we are dealing with CHEMICALS. Yes, that's right, CHEMICALS! they may be awesome, but as a disclaimer (though these are not volatile, nor caustic) I take NO responsibility for your stupidity. One of the chemicals is a TOXIN hazard. AKA don't drink it, it's not good for you. Also, the final blood product is kind of like medical iodine, it WILL stain, and takes a fair amount of washing to get the color out of your skin. No burns, but toxic, and stains. Act accordingly.
This might also not be something smart for children under 10. Stick with red cool-ade.
That said, let's have fun! This can be used for special FX in movies and not only Halloween! For hair raising blood effects, I've never seen anything like this! It's so crazy close to REAL blood that you'll have your neighbors dropping their mouths and dialing the local hospital for an ambulance!
Even better, this requires no pumps (heart included, we're not actually cutting ourselves)
So what DO we need?
Step 1: Materials
Two plastic spoons
stirring rods (can be spoons)
two containers to put your two part blood in. Should be easy to seal, and easy to carry.
Paint brush (optional, but recommended)
dull something to "cut" yourself with
Don't know where to get the chemicals? look here:
30g lasts a LONG time, and makes one heck of a lot of blood. Maximum you'll ever need is two bottles of each... unless you intend to bathe in the stuff... (see stupidity disclaimer)
