I know I saw this on here last year, and tried it for this year's party. I bought a bottle of red pool dye on Amazon.com. I took the cap of and cut an x thru the foil seal, and used and old facecloth as a "wick". Took the toilet cover off and tipped it on its side behind the float..it dripped blood red dye into the tank and every flush was blood red! My guests LOVED IT!!! Here is a pic...and no, it did not perm. stain the porcelain, however I did need some bleach the day after to finish clean up!
