Good! Good! That will help develop the kids' ingenuity! Poke 'em through end-first next time, kids.
We had slim table knives when the boys were young, and they discovered a knife would just slip through the kitchen sink drains. Eventually the drain stopped draining, and the trap was clear so it was plain that the clog was above the trap. Everything under the sink was one big maze of cemented PVC, so I took my hacksaw and cut the pipe above the trap. Surprise! I hit metal almost immediately and had to saw through about six of them.
