Dude...I saw the past year questions and the electricity related questions usually come first. So, i think that the diode question may be the long question as said by MAVtKnmj( pwewh....hard to spell)....
And oil viscosity may be the second...anyway, we have to be ready for any situations which may be different.
Anybody here have other hints or clues about the diode experiment? Any known materials.....
