Power of Plasma Balls Visualized | Dont wear a ring... Jumping wont help! Brainiac75 2024-04-27 | What happens if you wear a finger ring while touching a plasma globe? What if you jump while touching the plasma globe? Why are the filaments attracted to us? Is grounding - electrical earthing - needed to attract the filaments of the plasma ball?So many questions to answer but I will give it a try in this video.

TRUE YELLOW LASER or not? 25+ years wait over? // Valkyrie 573 donated by Tinker Lasers Brainiac75 2024-03-30 | Handheld, yellow lasers do not exist. That is my experience after I last year tried three that were advertised to emit some shade of yellow. None of them looked yellow to me...In this video, I give it another try. Can I fill the yellow gap between red and green with a new laser that should emit a wavelength right between the ones I have tested to be closest to yellow?Is it true yellow? How powerful is it? What is its true wavelength? How does it work? Will my camera recording in RGB (red green blue) even film it right?

MAGNETIC PAINT | Cheaper and easier than Ferrofluid and Ferripaste? Brainiac75 2024-01-27 | Ferrofluid is amazing. I wish everyone could experience it in real life, but it is expensive. Perhaps there is a cheaper alternative in your local store: Magnetic paint!In this video, I test the weird paint and compare it to ferrofluid and my own creation: ferripaste.

YELLOW LASERS?!? Finally - after 25+ years of collecting! Brainiac75 2023-09-30 | Welcome to what may very well be the most informative video on yellow lasers online. Simply because there aren't many yellow lasers around - making videos about them even rarer...After 25+ years of collecting lasers, I finally should have some too. Two new colors, supposed to be 561 nm and 591 nm, in the yellow gap between red and green.I will test their color (wavelength in nm) and power output. Are they as specified?Are they even yellow?

Monster magnet meets aluminum can... Brainiac75 2023-04-30 | Is aluminium magnetic? The simple answer is no. But in this video, I will show how aluminium actually will react in two different ways to a magnet.Using strong magnets and sensitive setups, even soda cans will have visible reactions. Do you know both of them?

New LASER Power Record on my LPM?!? | LaserCube Ultra 750K Subs Special Brainiac75 2023-02-26 | Time to beat my all-time laser power record! The latest and largest LaserCube should be the strongest laser I have ever tested. I will use a laser power meter and spectrometer to hopefully verify its specs.I will also open it up to see its inner workings and figure out the laser beam paths inside it. Quite complicated! This also means I can include instructions on how to open it up - for example to change the rechargeable battery after years of use. Perhaps the first time this has been published?Anyway, this was meant as something special to celebrate reaching 750,000 subscribers!

Measuring Monster Magnets Grade... Brainiac75 2021-03-26 | The grade of a magnet is important. It tells you how strong the magnetic material used for the magnet is. The higher the grade, the more expensive and powerful the magnet.However, measuring the grade is not easy. I have successfully tested it on 70x20 mm disc magnets, but what about my largest magnets: the monstrous Ø200x50 and Ø150x100 mm disc magnets?

What makes green lasers the BEST lasers? Brainiac75 2020-09-30 | Green lasers have both advantages and disadvantages. For safety reasons I have so far focused on telling about the possible infrared leakage from some types of green lasers. To a point where it seems like I wouldn't recommend green lasers at all...But I do! They have a big advantage that makes them awesome and maybe even safer to use than other lasers: lumens.
