Clean Bubble / Liquid soap

Clean Bubble
Clean Bubble

The World Health Organization says hand disinfection is one of the most effective measures to reduce the spread of pathogens, including the Covid-19 virus. Washing hands with soap for 30 seconds takes away 99.9% of the bacteria on the hands. BUBBLE is a device that releases a soapy liquid disinfectant that lets people lather to wash their hands, and its design and operation make the tedious task of hand washing fun. At the same time, children’s hand-washing habits were introduced and developed.
