The process of actually releasing earthquake victims from beneath broken sections of buildings takes a great deal of time and care. The Water Spider would surround the extraction process with less stress and urgency by taking care of one of the survivors' most immediate needs.
This is a water bottle with a capacity of 20 Liters. It can be carried to the site of natural disaster in which several people remain trapped. Eight tubes escape from the canteen, and they can be connected to tiny cameras if the resources are available. Each one is intended to reach a different person so that he can be given clean H2O for a better chance of remaining alive. The Water Spider can be collapsed for easy storage when it's not needed.
