When I look at the reaction, the powder that are used, have a really large surface. And the thinner the super glue is, the faster it dries and get hard.
Are cinnamon not more fine in grain size than baking powder by the way?Anyway. I actually managed to produce smoke from the use of cotton. I have no idea if that is too dangerous.
Also, the fumes hurt the mucous membranes in the nose and makes the eyes burn.
So getting too close are not adviceable at all.The dark or black powder in that kit you wrote about, might be powdered graphite. I might look for some of it and give it a test. Or perhaps toner from laserprinter.
And thanks regarding the PSU. I have no idea if it is safe enough, with my job on the 240v line. If insulation are good enough or something.
I just used my knowledge from electrician ground school about safety, and increased insulation and that stuff. Even modern PSU's with that switch, leaves the leads unshielded inside.
So I hope it is safer than generic factory made, CE labeled stuff.I guess getting shock by live wire is part of the job 😅. Last year repairing a dryer, and it has a broken solder joint and piece of a plastic (for holding the heater in place), so I grab the heater thinking I was unplugged it and I got zapped 😁. And that was one of many incidents 😅.
The live wire looks the same as the others, it just has a different grip 😀
The 3 body problems cannot be solved, neither for future quantum computers, even for the remainder of the universe. The Proton 2D is circling a planet and stepping back to the quantum size in 11 dimensions.
