I pop all the balloons from my previous video (but not the huge advertising one). I test their limits by sit popping and pumping them until they explode loud in pieces :D I do 3 sit pops, 1 pump to pop and 1 pump to pop while sitting on the balloon. The pump to pops are just insanely huge! I was impressed by the size of the balloons. Balloons in the video : Cattex doll, Roomtex Rocket, Kalisan 24", Qualatex 24", WB28 Longneck.
