Thread: I need ideas on this one, would you help?

I would like to know this for a project im doing.
What substance should I draw in.. say on a piece of paper, so that blood would follow it?

So say that X substance, if I draw a line on the table/paper and drop a drop of blood onto that line, that blood should fill that line up without going over too much.

Thank you for the help, and ideas.

first id like to say- "how strange" i only have one idea, water. if you dip a tooth pick in water and write with it on a piece of card board then accidently stab youself when modeling you warhammer the blood follows the trail, but the trail needs to still be moist, may or may not work.

This is a totally random idea... but what if you used a substance that attracted blood magnetically - using the iron in the blood as a possible magnet. Could work. Also remember that the blood could dry.

the magnet idea is cool, but i dont think it would work practically, as he wants the blood to follow the path, which i think would mean you would need to have the magnet increasing in attraction forces as the blood followed the path, maybe im wrong tho, ive never done anything like this, but its a cool idea I think water would be the best / easiest too, but I think all you need is a substance that will allow the blood to flow more viscous, or faster than the surface which you have put the blood, thats what i think anyway, so anything like water or stuff thats more "runnier" would work.

What about a substance that left a little rut in the paper or cardboard on which it was drawn on? Then the blood would follow the rut.

Draw a trail in thick glue on the paper and make a little hollow for the blood to run down

Wouldn't work - ionised iron in the blood isn't magnetic.

u should draw Cobalt Chloride
