Ubugcisa bokudala i-boomerang buyimpahla yamandulo. Kwixesha elidlulileyo e-China, ezi zixhobo ezinobhenkco ezikhangeleleneyo zasebenza njengezixhobo, ngoko ke isinyithi okanye imithi yayisetyenziselwa ukuyidala. Nangona kunjalo, imbali yale ndlela yezixhobo yaqala nangaphambili. Aborigines aseAustralia, abazingela iintaka, baqaphela ukuba ezinye iintonga ziyahamba, ngelixa abanye bebuya ngezandla zabo. Kuya kuba yinto engaqhelekanga ukuba loo mhlaba inqabileyo yendalo yayishiywe ngaphandle kokuqwalaselwa, kuba ukuzingela ngesixhobo sokuzibuyisela kuye kwalula kakhulu.
Namhlanje i-boomerang ekhangelekayo engabonakaliyo ithoyilo elihle kakhulu kubantwana. Kwiivenkile apho amaqela ahlukeneyo kwemveliso yabantwana athengiswa khona, umntu unokukwazi ukubona ii-boomerang ezenziwe ngeplastiki ngemibala eyahlukahlukeneyo. Izinto ezinjalo zamathoyizi ayithengi, kodwa ukudala i-boomerang ngokwabo akuyi kuthatha ixesha elide ekhaya. Ukongezelela, umntwana uya kuba mnandi kakhulu ukudlala i-boomerang, ekudalweni kwakhe.
Iphepha okanye ikhadibhodi - yiyo yonke into oyifunayo kulabo abangayaziyo ukwenza i-boomerang ngezandla zabo ngemizuzu embalwa. Le midlalo yokuzonwabisa iyathandwa kakhulu kubantwana, kwaye kunye nabazali babo, kuyavuya kakhulu ukubukela indiza yakhe kwaye ibuyele. Unokwenza ulungiselele ukhuphiswano olumnandi lokuphonsa endlwini okanye kwisitalato. Konke oku kuya kufumaneka kulabo bafunda inqaku lethu malunga nokwenza izandla zabo zamaphepha okanye i-boomerang yephephabhodi.
Ngoko ke, ngaphambi kokuba wenze iphepha le-boomerang, lungise iphepha le-A4 elifuneka lichithwe kwisiqingatha. Sidinga kuphela enye inxalenye yalo.
- Chaza i-bend ye-axis ene-axis. Sisebenzisa iindawo ezingezantsi kunye neyona ndawo ephezulu kwiphepha kuyo. Emva koko umsebenzi wonke kufuneka ulungele, kodwa sele sele uhamba nge-axis. Endaweni apho ikhonkco zifakwe khona, zibophe kumgca ophakathi. Ngoku siqondisa iimbombo kunye nomtsalane, uvula ingxenye engezantsi yomsebenzi wethu.
- Gcwalisa iinkcukacha kumigca yokudibanisa esiyiyo phakathi, ukugoba ingqimba engezantsi kwinqanaba. Inxalenye engasekhohlo iphakanyiswa kwinqanaba lama-90 degrees ukuya kwinqwelo, lijike ngokukhawuleza.
- Fold kwisiqingatha somgca we-axis iphepha, kwaye inxalenye egobileyo incitshiswa phantsi ukuze ufumane i-angle efanelekileyo. Siphinde sibole umgca ophezulu wesigxina esiphezulu se-boomerang. Kwifokethi eyenziwe phakathi, sizalisa ikhoneni lobuncwane bendawo engezantsi, e-pre-bent, ukudibanisa i-ironed. Inxalenye ephambili ngoku ikhuselekile ngokuqinisekileyo.
- Sifaka iingxowa ekupheleni kwephepha eliphantsi kwephepha. Gcwalisa iimbombo ngaphakathi uze uqonde ukongeza. Emva koko sibeka ikhoneni elingasekhohlo ngaphakathi kwinqanaba, kuqala ukuliguqa. Iphanga lenziwa kwipu yomsebenzi. Ngoku ugoba ikhoneni elifanelekileyo.
- Sigcwalisa iinjongo ezixutywe ngokufanelekileyo kwisalathiso, esakhiwa yi-valve ehlanganisiweyo. Sifumana ibhobho ye-boomerang kunye nokunqunyulwa. Ngokufanayo, sivula ii-corners kwi-ray ephezulu. Ngoku iphepha lethu le-boomerang elenziwe ngesandla lulungele ukuhamba!

Ngoku uyazi indlela yokwenza i-boomerang yephepha, kodwa ukungaphumeleli kwayo kukungabikho. Umdlalo owenziwe ngekhadibhodi uya kuba namandla. I-Boomerang ingenziwa ngamathathu, amane kunye namahlanu. Ngokwicwangciso esingezantsi, uhlala kuphela ekunqunywe kwikhadi elimnyama inani leenxalenye ezifunekayo kwaye ubambelele. Oku kubalulekile, kuba kuyimfuneko ukuqwalasela ukungqinanga komoya.
Ukongeza, ii-angles phakathi kwazo zonke ii-blade ze-boomerang kufuneka zibe zifanayo, kuba umdlalo wokudlala awuyi kubuya. Ungakujonga oku nge-protractor eqhelekileyo.
