Get started for free, and hurry—the first 200 people get 20% off an annual premium subscription.Speakers play music by magnetism. The stronger the magnet, the louder and better it will usually play.Makes me wonder what will happen if I take one of my super-strong neodymium magnets and put it behind a subwoofer. Will it play much louder? Does it matter what pole of the magnet faces the speaker?

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.

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?

Including potential misreads depending on the light source used.My Patreon-page: patreon.com/Brainiac75More about amber search lights: youtu.be/gNJAHwJwPLcMore about the 3W GTL3 UVC lamp: youtu.be/bb4t1F88mHsDid you miss one of my videos?: youtube.com/user/brainiac75/videosFULL MUSIC CREDITSTime codes: 0:01 + 10:06"Long Note Three" Kevin MacLeod (incompetech.com)ISRC: USUAN1100424Time code: 0:51"Lightless Dawn" Kevin MacLeod (incompetech.com)ISRC: USUAN1100655Time code: 4:55"Neo Western" Kevin MacLeod (incompetech.com)ISRC: USUAN1100615Time codes: 5:53"Perspectives" Kevin MacLeod (incompetech.com)ISRC: USUAN1300027Time code: 7:46"Energizing" Kevin MacLeod (incompetech.com)ISRC: USUAN1900040All music above licensed under Creative Commons: By Attribution 4.0 Licensehttp://creativecommons.org/licenses/by/4.0Time code: 7:16Mix of two tracks:1) The Shimmering by fran_ky (freesound.org/s/237363)Licensed under Creative Commons 0 license2) "Spacial Harvest" Kevin MacLeod (incompetech.com)Licensed under Creative Commons: By Attribution 4.0 Licensehttp://creativecommons.org/licenses/by/4.0ISRC: USUAN1100653#UVdetection #UVprotection
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? And can you guess which element will roll off a magnet the slowest: Aluminium, copper or silver?200x50 mm disc magnet, 50 mm sphere magnet and one of the 150x50 mm disc magnets donated earlier by https://www.magnetportal.de/My Patreon-page: patreon.com/Brainiac75Old video of mine on eddy currents: youtu.be/QJyWaliROPoOld video on how to improve eddy currents experiments: youtu.be/nz9N_RlFloMDid you miss one of my videos?: youtube.com/user/brainiac75/videosFULL MUSIC CREDITSTime codes: 0:01 + 11:07"Long Note Three" Kevin MacLeod (incompetech.com)ISRC: USUAN1100424Time code: 0:58"Energizing" Kevin MacLeod (incompetech.com)ISRC: USUAN1900040Time code: 2:12"Fluidscape" Kevin MacLeod (incompetech.com)ISRC: USUAN1100393Time code: 4:36"Perspectives" Kevin MacLeod (incompetech.com)ISRC: USUAN1300027Time code: 8:25"Adding the Sun" Kevin MacLeod (incompetech.com)ISRC: USUAN1900041All music above licensed under Creative Commons: By Attribution 3.0 Licensehttp://creativecommons.org/licenses/by/3.0Time code: 7:56Mix of two tracks:1) The Shimmering by fran_ky (freesound.org/s/237363)Licensed under Creative Commons 0 license2) "Spacial Harvest" Kevin MacLeod (incompetech.com)Licensed under Creative Commons: By Attribution 3.0 Licensehttp://creativecommons.org/licenses/by/3.0ISRC: USUAN1100653#Magnet #SodaCan #DrinkCan

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.
