If I had a prettier sink and hadn't lost my straw scrubber I'd really do it, but in this case we're going to use the power of imagination. This is in the running for Most Complicated Setup in a sippy cup, but really, it's not so bad. If Leak Proof is what you're after, there's going to be a few extra steps and barriers to work with. And then.... tragedy strikes. But once again, the parent comment crew comes to the rescue in parts 11 and 12!
