This is not like the old "SPIKES THRU BALLOON"! Insert a balloon into the tube, and then pierce it with two solid spikes. The balloon does not 'pop,' but remains inflated! Unlike the old model, you can show the inside of the tube, and your audience can see two spikes penetrating through the center of the tube. Balloon Penetration utilizes a brand-new principle that defies detection. The new method feels and looks absolutely fair, as if no gimmicks could possibly be involved. This is truly the ultimate version of the balloon penetration effect. Your audience will shriek when they see you thrust spikes through the balloon as no one likes to hear a balloon pop!
