Water stains warning / water stains warning

Water stains warning

Subways, airports and other public places will have surface water on rainy day. The accident occurs easily without setting warning marks in time. This idea uses the characteristic of Hydrochromic Ink which becomes visible when it gets wet, in order to remind passers-by to take care and avoid the slippery road in case of an accident.
