Lasers vs Lightning- Which Is More Powerful? | Highlights and Annotations by Gistr.

Military-grade laser: A high-powered laser with specifications and capabilities exceeding those typically found in commercial applications. Its use is often restricted to military or specialized industrial settings. Tesla coil: A resonant transformer circuit that produces high-voltage, high-frequency alternating current electricity. It's known for creating spectacular electrical discharges (sparks). Electrical resistance: The opposition of a material to the flow of electric current. Higher resistance leads to more heat generation when current flows. Amperes (amps): The unit of electric current, measuring the rate of electron flow. Higher amperage indicates a stronger current. Watts: The unit of power, representing the rate of energy transfer or conversion. Higher wattage signifies greater power. Electrical engineering: The branch of engineering that deals with the study and application of electricity, electronics, and electromagnetism. Ultraviolet (UV) laser: A laser that emits light in the ultraviolet portion of the electromagnetic spectrum, invisible to the human eye but capable of causing fluorescence in certain materials. Fluorescent tube: A gas-discharge lamp that produces light by passing an electric current through a low-pressure gas. The gas emits ultraviolet light, which then excites a phosphor coating inside the tube to produce visible light. Electromagnetic field: A physical field produced by electrically charged objects. It exerts forces on other charged objects. Liquid nitrogen: The liquid state of nitrogen, an extremely cold cryogenic liquid used in various applications requiring low temperatures. Gravitational potential energy: The energy an object possesses due to its position in a gravitational field. The higher an object is, the more gravitational potential energy it has. Capacitor: An electrical component that stores electrical energy in an electric field. Large capacitors can store significant amounts of energy. Infrared camera: A camera that detects infrared radiation, allowing it to "see" heat signatures. LASIK: A type of refractive surgery used to correct vision problems. The term is used metaphorically in the video. Science Bob uses a high-powered laser to incinerate a CD, showcasing the laser's intense heat and destructive capabilities. The slow-motion replay reveals the CD folding like a taco before being completely vaporized, highlighting the laser's power. ElectroBOOM then uses a Tesla coil to destroy his CD, creating impressive electrical arcs and showcasing a different method of destruction. Science Bob initially struggles to melt a block of ice with his laser due to the ice's transparency. However, by focusing the laser on one spot, he successfully bores a hole through the ice, demonstrating the laser's effectiveness when concentrated. ElectroBOOM attempts to melt the ice using a welding machine, creating a hot rebar knife. While initially successful, the rebar bends, and he resorts to sawing through the ice with the hot metal, ultimately failing to completely melt the block. Science Bob uses his laser to burn through a lipo battery, showcasing the laser's ability to quickly cut through the casing and release the stored energy. ElectroBOOM attempts to destroy a battery by connecting its leads with a low-resistance wire, causing a short circuit and generating heat. However, the battery's internal failsafe prevents it from completely self-destructing, resulting in a failed attempt. Mark Rober uses a crossbow to puncture the battery, causing an electron stampede and resulting in flames, providing a successful alternative method. -yeah, it was super ineffective. -that feels very disappointing. -well there are some crack here. -you know what I'm thinking? -so I called in an assist. it's like loosening the jar of pickles from my buddy Isaac Newton. -I thought everyone got one try. -you guys might want to step back. three. two. one. -oh my god. -oh no, I'm literally destroying the floor. -at best, you could argue that I turned this crystal ball into a bowling ball. -I think that's a win for glass. -Bob and I are no match for this thing. it's up to you. -it would all come down to whatever insane invention Mehdi had brought in. -we brought in a huge capacitor that can deliver 100,000 amps as much as one lightning strike, as much energy as a 50 caliber sniper rifle. -I think we get the point. -it can power 100,000 homes for a microsecond. three. two. one. zero. -and the test run we set up, -gosh, that was loud. -showed that he might have this crystal ball in the bag. -I've never done something like this before. three. two. one. I didn't expect that at all. -none of us did. -but maybe that's because we'd finally harnessed enough energy to destroy that dang crystal ball. -no way. -metallicized glass. -well, Bob, I think we've got to give this one to mehdi. -so does that mean he cleans it up? -winner cleans up. sorry, Mehdi. -Mehdi, added another to the score as we moved to the watermelon round. so Bob let us know what he was planning to do with his adorable little friend. -we're going to go all James Bond on this guy and go right down that. -googly eyes now suddenly seem much more sinister. -well, they were sitting around. I figured, why not? -we're going to leave this to you. -here we go! three. two. one. -but the highly trained "00-melon" didn't seem like he was going to crack. so Bob turned up the heat. -actually, that was kind of fun. -oh no! it's like lasik. -oh gosh, that looks horrible. well, would you want to see what it tastes like? -but all that and it only cut the watermelon about an inch deep. so I had to apply a little old fashioned elbow grease. -you said you work out? -clearly. -wow, that looks gross. -oh. -it has a hint of laser. -yeah! -refreshing. 100 degree watermelon. -Gordon Ramsay, watch out! -next up, was lightning. -you remember what I did to the crystal ball? -I do. -remember what I did to the crystal ball? -I do actually. -I'm gonna do the same thing to this poor watermelon; paint the room with watermelon. -this was one that might require the bulletproof safety barrier. -let's make the watermelon vapor melon. -three. two. one, zero. -on saber battle ever. -now I'll just go less crazy this time. light it up. -Mehdi, stop breaking things. -I've learned my lesson. I just wanna see how bright it gets okay? -that was delayed?! -once we got the lightning man a light bulb that was too big to use as a light saber it was undeniable that it was a pretty cool trick. -lightning lamp. not bad. all right, gentlemen, for my lamp, I'm doing a lava lamp as in a lamp that's filled with actual lava. -does Kevin the backyard scientist know you're doing this? -no! this is our little secret, Bob. -but the question was, could I actually get any in the lamp? -this is the moment of truth, can Mark do it? -because I only have one pour. and the anticipation had us feeling like Christmas morning. speaking of which, now's the perfect time to mention that if you want a Christmas morning reaction like this or this or this then a crunchlabs build box subscription is the answer because with the build box, not only do you get a super fun toy that you get to put together every month, but you do it alongside me while I teach you all the open. I could definitely get in there. I feel like I wanna run it one more time. three. two. one. -the safe door flew off the hinges, like a leaf falling off a tree, or a bird flying through the wind, or... -my money! -that's right. my money. -oh too bad, your money is blowing away. -I didn't think about the wind. oh, these were like hundreds! -put it in your pocket, here. -with all the interference from the win, it was hard to get a final tally, but I was pretty sure I could count more than $1. -well, I'm nothing if not a generous host. here is a little something for your efforts. -thank you, sir. -sorry, gentlemen. there can only be one winner. I'm just happy it was me. -hey, there are some electronics in there. what is that? - oh, watch out man. those could be live. -what did you put there? -now, you might have been just as surprised as me that the X factor actually won. but what should not hopefully surprise you after watching all the videos I've been making on my Youtube channel for 12 years, is that learning science and engineering doesn't have to be sucky and boring. which is exactly why I started a toy company called crunchlabs with the express goal of helping kids think like an engineer through monthly toys that get delivered to your door where you put it together with me. and have already shipped millions of these boxes. The data is in 87% of kids rated an eight out of 10 on a fun scale out of 10. but here's the dirty secret. more than three out of four parents said their child gained a new passion around stem and engineering from the boxes..-our secret sauce here, just like on my videos, is hiding the vegetables., so everyone leaves. Feeling stoked about the outcome..! on top of that,, each month,, your box has a chance to contain the platinum ticket. And if you get it, -Oh my god,!. -well,, then you're coming out here to CRUNCHLABS to build with me and my team for a day.., So, if you want to embark on this monthly journey with me and get a Christmas morning reaction like this,. just go to CRUNCHLABs.com or use the link in the video description where we're giving away those two boxes free as a holiday special.. thanks for watching..
