Ko te tauira whaipainga e whakaatu ana i tetahi raina whakatipu ngongo pepa, e whai ana ki te whakarato i tetahi raina whakaputa ngongo pepa ka pai ake ai te kounga tapahi o te ngongo pepa tapahi mowhiti. Ko te tohu nui o tana kaupapa hangarau ko te raina whakaputa ka whakauruhia ki te tapahi i te taha o waho, me te raina whakaputa mo te waahanga tapahi o te Tube pepa i mua i te tapahi tapahi.Ko te waahanga tapahi o te ngongo pepa e hinu ana i te taha o te taputapu.
I muri i te haunga, ko te waahanga tapahi o te Ko te ngongo pepa ka maroke tetahi waahanga, na te mea ko te pepa angiangi i runga i te mata o te ngongo pepa he whaikorero. Ka mutu te hinu, te wai ranei i te pepa, ka whakakiia nga puranga o te pepa ki te hinu. I te wa e tapahia ana e te kaita, te muka o te pepa angiangi, ka kore te muka e panaia e te tima hurihuri o te kaitahuri, kia pai ai te roimata o te pepa angiangi.
