How can the balloon can't break? The magician is in front of the audience with a metal needle to puncture the balloon, and the balloon does not blow away.
The performer has been treated with the balloon in advance: a little breathing of the sucking balloon is slightly removed, and then a 3 cm long transparent tape is attached to both ends of the balloon. The performer is in the right hand, and the balloon is inserted from the top of the rubber band, from the other end, the tape can make the "wound" no longer expand, so the gas in the balloon is very slowly leaked. Take a metal needle, gently bullet, let it float in the air, so that the audience see it "Enranu".
When the performer is inserted into the balloon again, he only heard "", the balloon is blown, because this time is not inserted from the tape. This second puncture is very necessary, because the balloon has "wound", the gas runs slowly, the balloon is getting smaller, so it must make it blown off with "extinguishing".
