Haha.
[Water] siphons stop working at about 0 C. -
SSteve4Physics replied to the thread A bead-mass oscillatory system problem.@Zayan, a few thoughts... This looks a relatively advanced problem – halfway between a simple pendulum and a double pendulum. It would...

Agree.
So in 1. is it anticlockwise cuz current induced between points C and B go from C to B and for 2. it is clockwise -
SSteve4Physics replied to the thread How to find eddy current (circular) path in this pendulum experiment?.I'm guessing you mean second finger - sometimes called the middle finger. (Maybe you don't want to appear rude!) It sounds right...
