Last night, I tried another product from Bubbles, the Queen Bee Bubble Bar ($4.95). It was a very, very pleasant bathing experience. The scent is a light mix of honey, apricot, and vanilla--not too strong or too sweet, just right. I see now that the site suggests using one bar for 2-3 baths, but I didn't realize that, so I used the whole thing. It created a huge amount of long-lasting and soft bubbles. The flowers and little bee that are embedded in the bar are made of sugar, so they dissolve right away and don't leave anything weird in the tub.
One caveat is that this bar was much harder than Lush's bubble bars, and was difficult to crumble up at the beginning. I had to soften it under the running water for a while before I could crumble it. This might be a problem if you want to break a piece off and use the bar for several baths. I will explore that later, as I have another Bubble bubble bar to try at home.
