Line 64:
A bubble is made of transparent water enclosing transparent air. However the [[soap film]] is as thin as the visible light [[wavelength]], resulting in [[Interference (wave propagation)|interferences]]. This creates [[iridescence]] which, together with the bubble's spherical shape and fragility, contributes to its magical effect on children and adults alike. Each colour is the result of varying thicknesses of soap bubble film. [[Tom Noddy]] (who featured in the second episode of [[Marcus du Sautoy]]'s ''[[The Code (2011 TV series)|The Code]]'') gave the analogy of looking at a [[contour line|contour]] map of the bubbles' surface. However, it has become a challenge to produce artificially coloured bubbles.

Adding coloured [[dye]] to bubble mixtures fails to produce coloured bubbles, because the dye attaches to the water molecules as opposed to the surfactant. Therefore, a colourless bubble forms with the dye falling to a point at the base. Dye [[chemist]] [[Ram Sabnis|Dr. Ram Sabnis]] has developed a [[lactone]] dye that sticks to the surfactants, enabling brightly coloured bubbles to be formed. [[Crystal violet lactone]] is an example. Another man named Tim Kehoe invented a coloured bubble which loses its colour when exposed to pressure or oxygen, which he is now marketing online as [[Zubbles]], which are non-toxic and non-staining. In 2010, Japanese astronaut [[Naoko Yamazaki]] demonstrated that it is possible to create coloured bubbles in [[microgravity]]. The reason is that the water molecules are spread evenly around the bubble in the low-gravity environment.
