The article reads: Several children required medical attention after drinking bleach that had been left in an unmarked soda bottle, according to both the parent and CBS.
I'll have to agree with Wenisrubber on this one.

Also, weren't the parents informed of what would be expected of their children before hand? And if they were told nothing, why would they let their child go?
I did recognize a couple of the boys from an episode of Dr Phil. It was about mom's pushing their children to act and model and stuff. There was a family with three boys and they made up a song about their mother called 24 hour b!@#h. The youngest boy was maybe 5 years old. The two oldest boys were on this show. That led me to believe these children are potential actors. Not that that makes it okay or anything.
I actually only watched the last 10 minutes of the first episode. It just seemed silly to me.
