grab your safety gear and sign the waiver,because weâ€™re exploring 5 insane science stunts you wonâ€™t be learning at school. normally we donâ€™t think of metals as beingvery dangerous. we use them all the time, but sodium metal is one thatâ€™s extremelyreactive. the second it touches water, it starts ripping the water molecules apart andreleasing hydrogen gas, which you can see is highly flammable, and in some cases, explosive.the vigorous reaction is exothermic, and gets so hot, itâ€™ll spontaneously burst into flames,and can explode. now, if a piece of wood is thrown on top, the elemental sodium blasts back withtremendous power, and sends the wood flying. now the reaction also forms sodium hydroxide,which is very caustic, and typically used
as a drain cleaner. but you might rememberfrom a previous video, we can tame that dangerous chemical with bacon grease, and make it intoa custom bar of shower soap. for this next experiment we need a plasticsoda bottle filled a third of the way with lukewarm water, and a little bit of liquidnitrogen. now if we pour a bit of the cryogenic fluid into the bottle and simply turn it upsidedown, the bottle blasts off with tremendous force. now weâ€™ve got a high risk, hand-heldrocket launcher. this works because the liquid nitrogen floats on the water and the gas canescape out the top. but when the bottle is turned over, the liquids trade places, andthe nitrogen is instantly vaporized, blasting water out the nozzle with incredible pressure.these bottles can shoot hundreds of feet at
high velocity, which apparently is enoughpower to break clean through my kitchen window. thereâ€™s also a risk of these blowing upin your hand, so why donâ€™t we move on to the next experiment while weâ€™re still inonce piece. now one way to super-charge a halloween partyis with a spellbinding blast-o-lantern. just pour a bit of calcium carbide into a smallplastic cup, then carefully set it inside a pre-carved pumpkin. when all the piecesof the pumpkin are back in place, simply pour in a bit of water, and put the lid back ontop. the pumpkin will slowly fill up with highly flammable acetylene gas. so as youmight be able to guess, weâ€™re going to light that off with a fuse. now when the spark hitsthe gas, it blasts out, a sinister looking
face, with a startling amount of power. yourguests will probably find this trick extremely amusing, because anytime you mix oxyacetylenegas with a pumpkin, itâ€™s bound to get a very spirited reaction. with some simple engineering, you can turna junk microwave like this, into an electrical metal melter, that will pump out a shocking800 amps, of metal melting current. we just need to break inside, to access the electronics,then locate this awesome piece of equipment .. a 1500 watt microwave oven transformer.now there are 2 coils on this beast. a primary and a secondary, and if we cut off the secondaryand replace it with 2 gauge insulated cable, weâ€™ve got ourselves an incredible devicethat will melt metal in just a few seconds.
when it gets turned on, it pumps out a staggeringamount of electrical current, which you can see is enough to reduce a machine screw, toa flowing river of molten metal. itâ€™ll also weld sheet metal, melt neodymium magnets,and heat steel until itâ€™s glowing hot, just in case youâ€™re in the mood for a littleamateur blacksmithing. for this last experiment weâ€™re making pie,but trust me, you donâ€™t want to eat this one. weâ€™ll need to take this recipe outsideand away from anything flammable, and get started by mixing precise amounts of sugarand potassium nitrate. this is a highly flammable mixture already, and the more we shake it,the faster itâ€™s going to react when we light it later on. now if we warm this powder onmedium-low heat, you can see the sugar begins
to caramelize and absorb the nitrate salts.when itâ€™s all melted and mixed together, it kind of looks like pumpkin pie filling,so why donâ€™t we try pouring it into a pie crust, and letting it set for a few minutes.if it werenâ€™t for the fuse sticking out of the center, youâ€™d think it was just aregular pumpkin pie. but watch what happens if we light it off. it bursts into a fountainof flames and spews hot ash like a miniature volcano. this gives a whole new meaning tothe term â€œpieâ€-rotechnics, and this just might be the first dessert, that burns itâ€™sown calories. well there are 5 crazy science stunts youprobably wonâ€™t see in the classroom, and while i canâ€™t recommend you actually trythese experiments, you know what would happen
if you did. thatâ€™s it for now. if you likedthese projects perhaps youâ€™ll like some of my others. check them out at www.thekingofrandom.com well, that was exciting. hey guys, i hope you liked these demonstrations.they are some of my favorites, probably because theyâ€™re a little bit dangerous, but thatkeeps it real. and if you felt the power and learned something new, then why donâ€™t youshare this video on facebook, and twitter, and reddit, because it really does help alot. now thereâ€™s one thing i need you to do rightnow. click on this video that alltime10s just released on their channel. itâ€™s showing10 crazy experiments that scientists did to
themselves. this is a video you need to see,and if you donâ€™t know who alltime10s are by now, you need to. they do some of the best top 10â€™s videoson the internet. they have a super popular youtube channel, with almost 3,000,000 subscribers,and as you might have guessed, this video is in collaboration with theirs. so go checkthem out, subscribe to them, and tell them that grant thompson sent you. now in the next couple of weeks iâ€™m goingto show you how to make miniature rockets that will launch off your desktop, so subscriberight now, if you havenâ€™t already, because iâ€™d really like to see you around in thoseproject videos.
are you still here? go check out alltime10s:)
