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.
Any ideas that you give me I will try out, and if that works Ill select you as best answer.

I have a question here and I need help. Please help me solve this problem and tell me the steps you took to solve it. Please and thanks in advance!

In 1980 the Wincon river was 32 feet below the bridge. Because of silt build-up in the river bottom, the river was only 20 feet below the bridge by 1986. Write an equation for the distance of the river from the bridge, "d", with t=0 representing 1980. If nothing is done about the silt, what year will the river reach the bridge?
