The goal of the experiment is to show that the visible component of electromagnetic radiation also carries energy, the absorption of which causes temperature increase of objects.
Which thermal camera are you using in this video? I'm working on a research experiment using lasers and thermal cameras but we can't seem to pick up the laser as clearly as you are able to
Also, how long of a time lapse takes place in the first video? You were able to increase the temperature almost 50 degrees C so I'm assuming this took a long time

Dear Kevin, we used Flir i7. I guess for this experiment it is essential to have a very good insulating pad (rather than an expensive camera).

It is in real time; the temperature jump comes within a few seconds.
Here is a whole description of the experiment: physicsexperiments.eu/4348/thermal-effects-of-laser-beam
