The Glow Bubbles bottle should be exposed to strong light prior to use. The longer and stronger the exposure - the better the results will be. Pour generously into running bath water and when ready&#44; turn out the lights. Relax and enjoy the soft Glow Bubbles. You may recharge the glow if you turn on the lights for a short time - but remember the results will be better if you close your eyes while the lights are on. So turn out the lights now and have a spectacular bath with your lover!<br />Glow in the Dark solution.
