Muaj tseeb txhua leej txhua tus tau pom yuav ua li cas hauv xinesmas lossis cov neeg ua yeeb yam tuav cov nplaim taws ntawm lawv txhais tes, lossis txawm tias juggle lossis pov nws. Thiab yog tias cov teebmeem tshwj xeeb hauv zaj duab xis tuaj yeem tsim siv cov duab hauv computer, tom qab ntawd hauv circus nws zoo li qhov txuj ci tseem ceeb tiag tiag. Qhov tseeb, qhov tshwm sim no muaj kev piav qhia txog kev tshawb fawb thiab hu ua "tshuaj tua hluav taws" los ntawm chemists. Yog tias koj xav tau, koj tuaj yeem surprise cov qhua ntawm kev ua koob tsheej los ntawm kev ua koj tus kheej.
Define in terms
Los ntawm cov nplaim taws uas tsis muaj hluav taws kub, chemistry txhais tau hais tias cov saw hlau cov tshuaj tiv thaiv oxidation uas pom lub ci ntsa iab. Yog li yog tias koj ua raws li cov lus qhia nruj me ntsis, qhov hluav taws kub tsis yog nplaim taws. Nws yog siv los tsim cov teebmeem tshwj xeeb zoo nkauj heev thiab qee yam ntawm cov foob pob hluav taws. Ib tug xov tooj ntawm esters thiab acids, ob qho tib si organic thiab inorganic, muaj peev xwm ua tau ib tug txias nplaim taws. Feem ntau siv ethyl derivative ntawm boric acid.
Feem ntau, hluav taws kub kuj txhais tau hais tias qhov pom "trick" nyob rau hauv cov txheej txheemtsis muaj combustion li ntawd. Nws feem ntau yog siv tsis yog rau kev dag, tab sis rau kev tsim qauv.
Txoj kev zoo tshaj los ua kom txias txias hauv tsev
Yog tias peb xav txog qhov kev xaiv nto moo tshaj plaws rau kev tsim cov nplaim taws uas tsis kub hnyiab, ces nws yuav xav tau cov khoom xyaw pheej yig heev. Ib diav ntawm cawv yog noj (kev kho mob lossis tshuaj dawb huv, siv rau kev tshuaj xyuas). Nws yog tov nrog ib tug sib npaug ntim ntawm boric acid hmoov. Nws, zoo li cawv, tuaj yeem yuav ntawm txhua lub tsev muag tshuaj. Ib tee ntawm concentrated muaj zog acid - hydrochloric los yog sulfuric - yog poob rau hauv cov tshuaj. Rau cov tsis paub: qhov no yog nchuav rau hauv cov roj teeb, yog li tau txais nws kuj tsis muaj teeb meem. Lub tais nrog lub workpiece heats li. Txoj kev ceev tshaj plaws thiab nyab xeeb tshaj plaws los ua qhov no yog nyob rau hauv ib qho chaw da dej thaum ub. Thaum sib tov ua kom sov, tab sis tseem tsis tau kub, koj tuaj yeem pib qhia qhov ua kom yuam kev.
Yog tias koj tsis tau ua hluav taws txias ua ntej, koj yuav tsum tsis txhob tso hluav taws ncaj qha rau ntawm koj txhais tes - yog tias koj tsis txawj, koj yuav raug mob. Nws yog qhov zoo dua los yob ib lub pob ntawm cov xov, tsau nws nrog cov muaj pes tsawg leeg thiab tsuas yog tom qab ntawd muab tso rau ntawm qhov hluav taws kub. Lub match (teeb) yuav tsum tsis txhob kov lub xov pob.
Ceev faj tshaj txhua yam
Cov hluav taws kub txias tsuas yog ntev npaum li cov ether tsim los ntawm cov reagents hlawv. Thaum nws khiav tawm, ethyl cawv yuav ua haujlwm ncaj qha - tab sis nws qhov kub thiab txias yog siab heev. Tsis tas li ntawd, tsis txhob hnov qab tias cov kua qaub koom nrog hauv kev tsim cov nplaim taws yog ib yam khoomtxaus ntshai. Yog li ceev faj:
- Tsis txhob nce cov tshuaj acid. Ua ntej, qhov sib tov tawg tuaj yeem tshwm sim. Qhov thib ob, koj tuaj yeem tau txais cov tshuaj hlawv los ntawm kev muab lub pob rau hauv koj lub xib teg.
- Nco ntsoov tias tsis muaj cov plaub hau lossis ntug ntawm cov khaub ncaws ze ntawm lub pob taws. Tus kws yees siv tsis tau paub txog yuav tsis ntes tau lub sijhawm thaum cawv kub hnyiab, thiab tej yam uas tau hais los yog nplaim taws.
- Khaws ib lub thawv me me, tsis muaj hluav taws kub nyob ze los npog thiab tua hluav taws kub thaum lawv kub. Los yog ua kom yuam kev hla lub chav ua noj dab dej kom sai sai muab pov rau hauv nws.
Tom qab qee qhov kev cob qhia, thaum koj kawm tswj qhov kub thiab txias hloov mus rau qhov uas koj tsis kub hnyiab, nplaim hluav taws tsis kub tuaj yeem taws rau ntawm koj txhais tes.
Kev xaiv nyab xeeb
Koj tuaj yeem ua rau hluav taws txias rau lwm txoj hauv kev, txawm hais tias nws yuav zoo li tsis tshua muaj txiaj ntsig, txij li cov nplaim taws los ntawm nws muaj qhov qub, tsis muaj xim ntsuab, xim. Ib daim ntaub me me ntawm paj rwb yog muab, dov rau hauv ib lub pob thiab qhwv (lossis zoo dua, stitched) nrog cov xov kom nws tsis nthuav tawm. Cov roj uas kub kub, xws li isopropanol, yog nchuav rau hauv lub tais ntiav. Koj tuaj yeem nqa cov roj av rau lub teeb, tab sis ntawm no koj yuav tsum tau ceev faj: cov kua dej no muaj qhov sib txawv ntawm qhov sib txawv, koj tuaj yeem khiav mus rau qhov pom tseeb heev. Lub pob ntaub yog dipped hauv roj, nyem tawm thiabyog teem rau hluav taws. Lub pob yuav sov koj txhais tes, tab sis yog tias koj dov nws hla lub xib teg ntawm koj txhais tes thiab ntawm koj cov ntiv tes, koj yuav hnov zoo li sov so xwb. Thiab yog tias koj lubricate qhov chaw uas lub pob yog nteg tawm nrog qab zib, ces koj tuaj yeem khaws cia rau hauv ib qho chaw. Kev ntsuas kev nyab xeeb nkaus xwb tsis txhob kov saum nplaim taws - qhov no yog qhov kev tiv thaiv kub hnyiab.
Short nplaim
Tseem muaj lwm txoj hauv kev yuav ua li cas ua kom kub kub ntawm koj tus kheej txhais tes, feem ntau yog raws li tus kws ua khawv koob dexterity thiab me me tricks. Txoj kev yooj yim tshaj los siv ob txoj kev xaiv:
- Sib tov cawv lossis acetone nrog dej kom muaj qhov sib xyaw ua kom cov kua kub hnyiab, tab sis tsis tawg. Tes yog lubricated nrog ib tug tshwj xeeb hluav taws-resistant gel (muag nyob rau hauv lub khw muag khoom tshwj xeeb hauv props thiab tswv yim tso dag). Roj yog poured rau hauv lub nkoj los ntawm xib teg ntawm koj txhais tes thiab teem rau hluav taws. Hais lus nruj me ntsis, qhov no tsis yog hluav taws kub, vim tias qhov kub thiab txias yog tus qauv, thiab nws tau tswj xyuas tsis muaj mob tsuas yog vim cov gel. Tab sis nws zoo li impressive thiab convincing.
- Cov ntaub nyias nyias yog saturated nrog vodka, thiab cov vapors yog ignited thaum cov teeb meem kis tau rau ntawm koj txhais tes. Cov phuam qhwv caj dab ntes tau hluav taws, tab sis vim yog cov dej cawv tsawg, nws tawm mus ua ntej hlawv daim ntawv. Qhov kev lees paub ntxiv ntawm kev nyab xeeb yog ua kom koj lub xib teg ncaj li sai tau.
Imitation nplaim taws
Nws tseem xav txog qhov cub hluav taws kub. Hauv tsev, tsis muaj peev xwm nteg lub qhov cub tiag tiag, ntau tus neeg nyiam nyiam ua li ntawd. Lub kiv cua tau muab tso rau hauv ib lub thawv (koj tuaj yeem siv lub thawv ntawv) kom cov cua ntws los ntawm nws tau qhia.nce. LEDs thiab cov ntxaij lim dej ntawm cov xim liab, xiav thiab daj yog muab tso rau hauv cov ces kaum. Muaj daim iav ntawm ob sab. Daim duab peb sab yog txiav los ntawm cov ntaub thiab glued mus rau lub thawv. Lub kaw lus tau ntsaws rau hauv cov qhov (socket) - thiab cov nplaim taws txias ua rau muaj kev nplij siab hauv chav.
