Now, after ten years of experiments and discoveries, we have done what scientists claimed was impossible... we've combined the simple joy of bubbles with the beauty and magic of color, inventing the world's first real colored bubbles. Disappearing color. Non-staining. Non-toxic. Vivid colors.

UPDATE: Bought small bottles of pink and blue. Effect wasn't as cool as I expected it to be. The colors are not so bright, maybe they will look better outdoor. But when used indoor these bubbles definitely make moms nervous even after they shown that color of the ink disappears after some time.
