I've done this test twice and I still can't figure it out.
The first time, I put a strand of hair in the glass but pushed it down far enough to break the surface of the water. The hair sunk pretty quickly. When I checked on it 5-10 minutes later it was floating again.
The second time, I put 2 different strands on top of the water -- one 4a and one 4b. This time I let them sit. The problem this time was that because of the coils and bends, not enough hair was touching the surface of the water and therefore would never be able to absorb enough water to properly do the test. (Only the places where the hair bent touched, otherwise the rest was clear above, for the length of the strand.) The strands stayed in this position for about 3 hours, at which point I gave up.
So does this mean both tests were a bust?
