I always wanted to use the water that was getting wasted. When it rains there is water everywhere. But what does one do when he/she is thirsty? We carry an umbrella and I often wondered what I could do with it. That's when the idea struck me. Stay protected and have water to drink.

The concept : An umbrella which I worked on could double up as a water storer. Costing only about Rs. 20 more, it is also viable. Water hits the umbrella when it rains and that goes down through a pipe and gets collected in a bottle. This water is 100 per cent pure being the first shower.

Future plans: while the patenting is under process Ojasvi does not believe in waiting. His head is bursting with ideas and he is planning on making a nautomatic drink stirrer.
