Worst Bath Fizzer I've Ever Used

When dropped into the water it very literally did nothing. No scent, just sinks to the bottom and slowly dissolves. The "icing" of the donut actually didn't dissolve at all and just broke off into tiny bits and pieces that floated around in the bath. When I drained the tub, I had to use paper towel and a cleaner to clean the remaining bits off the sides of the tub because they left an awful purple stain behind. Stay away!
