In this video, you can again see the 'flash' spread across two frames.

Just after the 2m42s point there is a very sudden change of colour. In less than two seconds it appears that the rod changes state. Below is the moment in question where an overall saturation change has been made to emphasise the moment.

This colour saturation version has been uploaded here for you to study.

At the end of the video, there is an attempt to make steam with water from a syringe.
