This project is an expansion on the one in which we put drops of liquids onto waxed paper. (C121.12)

We have some different surfaces onto which to put our drops. They are like waxed paper, in that they are not absorbent. These are aluminum foil, glass, blocks of paraffin and plastic wrap. Do the drops react the same on these surfaces as they did on the waxed paper? We can compare the reactions by making profile charts on the liquids dropped onto these surfaces and comparing them to those we made on the drops we put onto waxed paper.

Just for kicks, let's put some drops onto a piece of unfinished wood and see what happens. We'll want to look at the clock and note the exact time when we put the drops onto the wood. I won't tell you why; it's a mystery!
