>>2373180>>2373324I don't think it's possible to make them go pop, but I took my brother's Challenger K2 onto the lake last week and it already got a puncture after its first outing. I don't think this happened in the water, btw, but probably when it dragged on the pebble beach or when I propped it up on its side to install/remove the keel.
Tl;dr: they are very fragile.
