A US inventor has spent 10 years of his life, and over £2million, creating the world's first non-staining, coloured bubbles.

Tim Kehoe says that for the past ten years he has been conducting experiments to perfect his vibrant coloured bubbles, dubbed Zubbles.

Bubbles have traditionally remained clear because their form - layers of soap and water - means most colourings do not have any impact. Those that do, stain whatever they come in contact with.

But Tim has created a dye which allows the bubbles to hold their bright colours until they pop, with the colour then fading in 15 minutes ... just long enough to scare dads who think their white shirt has been ruined.
