Tenyo - Balloon illusion | Zaubertrick

Insert a balloon into the tube and pierce it with two solid spikes. The balloon does not "pop" but remains inflated! Show the inside of the tube so that your audience can see two spikes penetrating through the center of the balloon. Remove the spikes, and show the balloon to be completely, and amazingly unharmed. Truly the ultimate version of the balloon penetration effect. You are supplied with 20 spare balloons for 20 performances.
