The magician shows a clear balloon blown up by one spectator from the audience, and then the magician shows a 45-cm long stainless steel needle to be looked at by the audience. Using this needle, the magician plunges the needle into the balloon from one end to the other and the balloon does not burst out !!
A full set including a special needle, 10 colourless balloons and directions. A very easy magic trick to perform.
