imperative...
I know you probably already have a plan or two on your experiment,but after seeing Chuckie's video(with Axelrod),I thought everything was covered EXCEPT squeezing out the Mop(that lay hidden in the concrete mixer)into a jar and measuring the amount of oil picked up by the sorbent.The video "suggests" that the Mop cleaned the sand of the oil,but it wasn't confirmed via measuring as was the water.That was the missing part of the whole experiment and it left a hole for doubt to creep in(along with never seeing the Mop sorbent inside the mixer.
All that was shown was a bit of sand and the full amount of water left after the demo.It's the OIL that needs to be measured.That will tell us what is left in the sand,if any.Forget the water...
just a thought....
