I remember growing up being taught that training for football(soccer) in the dark was a great way to get ahead, a way of training your eyes to work under all conditions, and giving your reactions a work out. Those days are potentially long gone, Nike and Pierre Haulot, have created ‘Virtual Park’, a glow-in-the-dark spray paint that can be used to transform any environment you need to keep practicing in the dark, the potential outside of sports for this product is huge also for the paint that lasts just 2 hours to deter vandalism. Thanks to Complex.
