Underwater Respirator

The Under-Water Respirator was a device designed by Ben to give a single breath to its user. The device, as implied by name, is for use underwater and was used by Anthony in Week 2 to place a shape charge to save the SGK Base from flooding.

Principle of Working
The device was made using an empty garden sprayer. The sprayer canister was pressurized by the pump, and the hose was attached to a snorkel mouthpiece. The trigger on the hose regulates the amount of air going into someone’s lungs. When a breath was needed, one puts the hose to their mouth and gives themselves a “shot” of air by pressing the trigger. This gave them approximately 45 seconds of extra time under water.
