I-Magic 8 Ball ibonakala sengathiinomlingo, kodwa ukusebenza kwayo kusekelwe kwisayensi elula, ehlakaniphile. Akukho mlingo, kuphela umklamo ohlakaniphile.
Ingaphakathi lebhola ligcwaliswe uketshezi oluluhlaza okwesibhakabhaka olusekelwe otshwaleni. Lolu ketshezi olumnyama lunenjongo eyodwa ebalulekile: ukufihla zonke ezinye izimpendulo zingabonakali, ukuze kube yimpendulo eyodwa kuphela entantayo ebonakalayo.
Ukuntanta ngaphakathi kwalolo ketshezi kukhona idayisi leplastiki elimhlophe elinamacala angu-20, elaziwa ngokuthi i-icosahedron. Ubuso ngabunye kumacala angu-20 bunempendulo ehlukile ephintiwe kuso ngezinhlamvu eziphakanyisiwe. Ngenxa yokuthi idayisi alinalutho futhi liqukethe umoya ovaleleke ngaphakathi, linobunzima obuphansi kakhulu, okulivumela ukuba lintante phezu koketshezi.
Lapho unikina ibhola futhi ulijika, idayisi lintanta phezulu futhi elinye lamacala alo angu-20 licindezela libe isicaba ewindini elikhanyayo. Uketshezi olumnyama lugeleza lusuka ezinhlamvini eziphakanyisiwe, okwenza umbhalo omhlophe wempendulo ubonakale ngokucacile ngemuva okumnyama.
