Brainiac75It is time to test the strongest lasers in my collection, now that I have both a laser power meter and spectrometer. I can test both power and wavelength of the strongest laser for each laser color I own. I have 11 colors in my laser rainbow, so hang on for an epic journey into the lasers in my collection. Many of which I haven't shown in a video before!

#LaserCollection #Spectrometer #Brainiac75Power of Plasma Balls Visualized | Dont wear a ring... Jumping wont help!Brainiac752024-04-27 | 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. Luckily, plasma balls are relatively safe sources for high-voltage experiments :)
#plasma #highvoltage #sparkTRUE YELLOW LASER or not? 25+ years wait over? // Valkyrie 573 donated by Tinker LasersBrainiac752024-03-30 | 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? Let's find out!
#yellow #laser #mysteryLASER underpowered by its power supply? | First TTL/PWM Arduino attemptBrainiac752024-02-24 | My yellow-green laser module is not even close to performing as advertised. Perhaps because the power supply is less powerful than advertised too? In this video, I max test the power supply and see if it matters. I also build a pulse-width modulator using an Arduino Uno in an attempt to adjust the laser's power output. Will I succeed?

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. How well does magnetic paint work in comparison? What are the fluids' strengths and weaknesses? Is one of the disadvantages of paint actually a useful feature? Let's find out!

#magnetic #paint #ferrofluidMystery RADIOACTIVE Source | Can we identify it?Brainiac752023-12-30 | How do you identify an unknown, radioactive element using affordable tools? I am faced with this challenge from an unlabeled radioactive source. It is radioactive, but what makes it radioactive? In this video, I use a range of tests in an attempt to identify the radioisotope. Including paper, magnets and a gamma spectrometer. Will I figure it out or will the source remain a mystery?

#radioactive #radiacode #geigerUpgrading Fiber Optic Lamps to LASER Brightness!Brainiac752023-11-26 | I like fiber optic lamps but their brightness always disappoints me. They are too dim to really impress me. No matter if it is an old halogen or new LED type. Time to upgrade my two fiber lamps! Make them brighter - much brighter. Will I succeed or is there a limit I overlooked?
#fiber #lamp #laserMonster magnet meets monitors...Brainiac752023-10-28 | What will happen if a strong magnet is put near a monitor? In this video, I will test two screen technologies: old-school CRT and flat-screen LCD. They will meet my largest, strongest magnet and respond in different ways. Will they even work after the challenging tests?

#Magnet #Monitor #CRTYELLOW LASERS?!? Finally - after 25+ years of collecting!Brainiac752023-09-30 | 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? This may depend on the eyes of the beholder. What do you think?
#Yellow #LaserMessing Up the Fluorescence of Tonic Water - in several ways...Brainiac752023-08-27 | How delicate is the fluorescence of tonic water? In this video, I test several ways of affecting the light output of tonic water and try to explain how it all works. Turns out that the fluorescence of tonic water is a happy, coincidental combination of the right factors for quinine!
#fluorescence #tonicwaterGLOW-IN-THE-DARK: Can you change the color?Brainiac752023-07-30 | I have always been fascinated by glow-in-the-dark items and still am. But is it possible to change the color of the light the pigments glow with at night? For example by changing the light used to charge them - on both wavelengths and spectral bandwidth? And how about changing the temperature of the pigment? Time to find out!
#Glow-in-the-dark #Fluorescence #PhosphorescenceDesert Sun Lamps! | My least healthy lights yet?Brainiac752023-06-30 | I have some fluorescent lamps that look ordinary - but they are not! They are designed to simulate sunlight in a desert. What makes them different and why were they designed like that? It is actually a dilemma of life. Let's explore it!
#FluorescentLamp #FluorescentLight #UltravioletAre cheap UV detection cards any good?Brainiac752023-05-28 | How do you spot ultraviolet light? A cheap way is UV indication cards but is a cheap way a good way? In this video, I test three different indicators with six different lights. I also show how it is possible to use the cards to test if your glasses have UV protection. Including potential misreads depending on the light source used.
#UVdetection #UVprotectionMonster magnet meets aluminum can...Brainiac752023-04-30 | 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?

#Smartphone #Gaussmeter #EarthNew LASER Power Record on my LPM?!? | LaserCube Ultra 750K Subs SpecialBrainiac752023-02-26 | 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! Thank you so much!

What's inside it? And why are there stairs inside the demagnetizer opening? According to most sources the stairs are important, but the explanations are vague at best. In this video, I will do some investigation and open the tool to finally figure out how it really works! And show how you don't need the tool if you have a bar magnet...
#Magnetizer #Demagnetizer #ToolCOLA is PERFECT for lowering a lasers power!?!Brainiac752021-08-29 | Lasers are just getting stronger and stronger, but sometimes you want to lower the laser beam's power. For example when measuring beam divergence or setting up an optical system safely. In this video, I will test some of my viewers' suggestions for lowering a laser beam's power. Including using my favorite drink: cola! Will it work? Will it even be the best choice?

#Radioactive #SDcard #YourwaytospaceMeasuring Monster Magnets Grade...Brainiac752021-03-26 | 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? Let's find out!

#Plasma #Magnet #Brainiac75What makes green lasers the BEST lasers?Brainiac752020-09-30 | 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. I explain how in this video.
