Arsenic

-insert evil laugh- Mmm Cyanide, it comes in all kinds of different flavors like umm Rainbow Cyanide and Kool Aid Cyanide and yeah you should have a glass of Kool Aid Cyanide with me (:

Woo go nothing~!

My thesis on Arsenic is that we should not have it in our water supply since it can have devastating effects on the normal people of todays society perhaps death if taken repeatedly for a long period of time and should not be consumed or in our water supply good day sir.
