I tried the Lush Marathon Bar Bubble Bar last week, and unfortunately it didn’t live up to all of the hype.
I crumbled about half of the bar into a warm tub, and I only got a few bubbles, all of which disappeared as soon as I actually got into the tub.
That’s definitely not my idea of a bubble bath - I want my bubbles to stick around forever.
The web site does say “The stronger your water pressure, the more bubbles you will make, so you might not need the whole bar.”
I think we have a normal amount of water pressure, so I don’t think I can blame the lack of bubbles on that.
Although the Marathan bar didn’t smell like “minty cinnomon” to me, I did like the smell.
Some people have had problems with Lush bath bombs and/or bubble bars staining their tubs, fortunately, I didn’t have a problem with this.
There’s nothing that can ruin a nice relaxing bath like knowing you’ll have to scrub the tub as soon as you get out.
