When you take 60'' balloon you know that it’s big. But we had no clue how huge it could become! So it’s time to know that;) We attach a pump and turn it on! The balloon is growing, growing, growing... larger and larger! It becomes so freaking tight and huge that even the 72'' Room balloon looks tiny compared to that! And finally... BOOOM!!! An epic burst that nearly breaks the windows! Wow that was the mightiest pumping to pop we’ve ever did!
