From Lush, the Lemon Bubble Brush: "The tub is your easel, the bubbles your canvas. Hold Lemon Bubble Brush under the tap and fill the air with a lemon, lime and orange scent as you fill the tub. Once you have a mound of Hollywood-style froth, take your brush and delicately sweep, swirl and swish it along to create rays of sunshine, yellow brick roads or fields of fluffy sunflowers." $7.95, also available in Mint and Candy. (And also on my Lush wish list: Whipstick lip balm, with dark chocolate and tangerine oil.)
