Drano is a very strong chemical you pour down the drain (funny that! LOL)...it acts like an acid, burning away anything that may be blocking the drain. Not a nice thing and it will burn your skin if it gets on you...I've heard of the fumes burning people's throats also so do not inhale it! Best to stay clear of it altogether.

Btw, I tried out 11 different gender tests and 9/11 said girl. They're all on Bunny's website if you're interested
