One step against the pandemic
TOUCH FREEE HAND SANITIZER/LIQUID DISPENSER
Thank you for stopping by my social Project website. I have a curious mind, always inquiring about the world that surrounds me, and seeking for opportunities to solve problems. This time, I made a touch free sanitiser, but with a twist: it's CHEAP;Under 300 rupees kinda cheap. I designed this with a goal in mind: to distribute these dispensers at old age homes for the safety and well being of the elderly citizens. TO check out the social initiative, click here.
