Blinking Led without any active components

In this video I'll show you how to make a blinking LED without any Transistor, IC or without self blinking LED
This circuit is a RC Relaxation oscillator and it uses delay of LDR's delayed
reaction against Light. So; phototransistors or Optocouplers cannot work in this way.
This circuit designed to Blink in dark. So at sunlight it dont blinks.
Power consumption is very very low that, this circuit can work for years with just two AA batteries.
It can be used as fake alarm outside of your House.
Thank you.
