Sword thru balloon

Truly the ultimate version of the balloon penetration effect.<br />
Insert a balloon into the tube and pierce it with two solid spikes. The balloon does not &quot;pop&quot; 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. &nbsp;<br />

&bull;&nbsp;You are supplied with also with a small number of balloons and a mini inflator.
