[Phys-L] Polarity of a 1F (super) capacitor


I have recently purchased several 1 F electrolytic (super) capacitors for
several labs and demos. However, I am having trouble discerning which side
is positive for the polarity of the capacitor. I note the the cap has a
long and short connector, but there is little else (such as an arrow etc) to
clearly define the polarity. Before I accidentally reverse the polarity
while charging does anyone with a 1F cap have any insight for me to
guarantee the polarity direction?
