1.5V battery blinks 2.5V LED..Impossible?

This 1.5V battery LED flasher circuit is very popular YouTube, it seems simple… but how can we flash a 2.5V LED from a 1.5V battery? In this video we will take a closer look at this brilliant circuit, I will explain how the circuit works, simulate it with LTSpice and we will check the real circuit operation on the oscilloscope.
