Candy Addict has the top 10 list of gross candies. Here's no. 8 Sour Flush Candy:
The candy in this is nothing special - it’s powdered candy (like Pixy Stix) and a lollipop. It’s all about the presentation though. The powdered candy comes in a realistic plastic toilet and the lollipop is flat on the end so it looks like a toilet plunger. Lick the plunger then dip it into the toilet to get some candy on it. Yum!
