Diesel audio capacitor scam
This is the innards of a Diesel Audio "NS-2.2" car audio capacitor.
The big metal can is what you see on the outside, the far smaller toilet paper roll thing is the actual capacitor. The rest of the can is mostly empty space aside from a few inches of black epoxy at the bottom to give it some artificial weight.
I did a very rough capacitance test by measuring the discharge time through a 12-ohm 10-watt resistor - I get an RC constant of about 2.5, which works out to an actual capacitance of around 0.21 farads instead of the 2.2 advertised.
