Just had this recommended to me and thought it was pretty cool
The theory and maths of Quantum computing is waaaaay above my head but I find the subject super interesting none the less and she does a really good job explaining it in layman’s terms

The final laser illumination seems to push that foil way too fast. All you need are a few molecules of air to generate the helping Crooke's effect you get in low air pressure environments. That setup is just too insensitive and doesn't have any true measurement or math to back up what you see as being true sole light radiation pressure. (I guess unless he is using a 100-500 watt laser, that foil is just moving way too fast..)
Now for the real-Mcoy, a video from Cody's Lab. He created a sensitive enough balance scale, calculated the power of the source laser light attaining the predicted force of the light, created a calibration weight (10x that of the light pressure on a mirror surface) to calibrate his balance scale, then measured the light's force VS the calibration weight and found a close enough match that you know what he measured was real:
Clever experiment setup from Cody.
Now I know how to make a super sensitive scale with nothing but passive mechanical elements and a magnet, thanks.
In the Cody's experiment, I would have also aimed at the Al foil through the glass bottle while missing the reflecting/absorbing target, and also made yet another measurement with the mirror tilted 45 degree, in order to check if the point where the laser first hits the glass is heaving any influence or not.
Don't know about the xofunkox's experiment, but he is certainly aware about the possible influence of air molecules. All his videos are without any further explanations and very short, with only 1-2 minutes filming various physics experiments and apparatus, so no surprise that there is no effort to convince others that the experiment was conducted properly.
About the foil acceleration seen in xofunkox's experiment, seems plausible when compared with Cody's experiment, since Cody's instrument was heaving a huge mass to move, when compared with just a thin foil under a high vacuum bell.
You've probably heard of SWR standing wave ratio on transmission lines, but what about explosions in tunnels?
