Circuit Experimentation - NAND Gate LED Flasher

In this circuit experimentation page, we reverse the capacitors so that the anode side connects to the gate output. Since the output is a positive voltage it should charge the capacitor well. However, this time the cathode side, which is negative, connects to the gate inputs. You will see that the circuit works just as well with the capacitors in reverse. I would like all the geniuses with an overpriced education to explain why it still works. Perhaps we could make it a huge forum debate.

This time, try the same experiment with the SN74HC00N IC to see if it still works with the capacitors in reverse.
