Hey, you know what's worse than having a bowlful of super absorbent polymer balls* in your kitchen with eyeballs looking out at you? 

 When your kid decides she doesn't want a bunch of them that have dried up and thinks it's a good idea to dispose of them by dumping them down the bathroom sink and you figure it out two days later because you happen to walk into the downstairs bathroom and step in a puddle of water on the floor.

 Dormouse: "Yeah, but they were all moldy, so I had to throw them out."

 *incredulously* "And you threw them down the sink?"

"Yeah, what's wrong with that?"

"Think about it.  What also goes down the sink?"

"Just water."

"And what happens when these Orbeez come in contact with water?"

"They swell up and... oooooh."

So, yeah, I spent half the day cleaning water up off the floor and taking the drain apart to try and extract the clog of Orbeez beads from all our pipes because School for the Gifted was too lazy to walk into the other room and throw them in the trash.  Hint: a vacuum cleaner hose doesn't work no matter how much you want it to so don't even bother. 

The sink is finally back together now, but it leaks.  I'm leaving that for The KingofHearts to fix when he comes home because it's half his DNA, after all.

All I have to say is at least she didn't put them in a fish tank.
