I do think it qualifies as a debate. I may be wrong, but I saw this as an attempt to go to the extreme in order to establish a border from which we can shrink inwards toward a conclusion. The debate being, “Is water detrimental to a pipe, or not.” There are plenty of variables, and this fun experiment doesn’t deal with many of them, but the results will be very interesting, even outside of the “detrimental or not” debate. Experimenting is fun! As is debating. I’m having a great time following along.
