I was surprised by this. With a video that is 17 minutes long, I expected mostly 'blah blah blah' and 5 minutes worth of inflating the balloons before the payoff, like so many 'what will happen' videos I have seen in the past.

At 0:41, I think this is not what they meant when they said the pen is mightier than the sword, but it does make sense in this context. I thought it was just gonna get one balloon, but it got six!

Slow-motion makes them look like they are melting or dematerializing. The guy with the fishing rod missed a balloon because the hook began sliding through the floor on one point, and got through the side of the 'missed' balloon, but poked through the rest of it.
