Project Name : Storm Alarm from Leeches
Theme Name : Disaster Management
The project is based on Henry‟s Law which states that “The solubility of a gas in liquid is directly proportional to the partial pressure of the gas above the liquid.”
Before a storm pressure starts to decrease this causes some oxygen in the water to escape. Therefore some organisms like leeches come out of water to take more amount of oxygen. In the exhibit as soon as they come out, they come in contact with the trigger, thus starting the alarm.
This simple model, if employed in areas where alerting system is not good can save many lives as it can be used as an effective storm indicator which predicts bigger storm more accurately.
