Watch
What: This watch conceals compact inflatable bag. If you are in danger of drowning, you can blow it up to stay afloat. In
more dangerous and treacherous waters, a cord can be pulled which automatically fills the bag with gas. This ‘auto-fill’
is only a one time use. The device can also be used for telling the time.
.
How: The bag can easily be inflated by blowing
into it through the mouthpiece. This works on a simple and obvious principle. The rip-cord that automatically inflates the
bag uses combustion. It is explained on the following further on

Combustion is the complex burning process of chemicals to produce a large amount of gas. In the type of process
that takes place here, heat will be produced, rather than light. As such, there is a danger that the water around the bag
will be heated. Theoretically, since heat rises, and your body temperature will be lower than the inflatable bag, you may
be ripped apart by the pressure created. Another problem is that if the cord is pulled in the wrong manner (too fast) and
a rip in the bag is caused, the presence of other chemicals in the air may produce a very unstable reaction. What will scare
most people off buying this sort of thing is the fact that basically; their watch is a bomb. It would most probably be restricted
from airports and even some public venues.

The reason my device is such an asset to the future is that it is predicted that the polar ice-caps will eventually
melt. This will mean that many islands and even some countries will completely covered with the excess of water. Although
it’s a long shot, this watch may just save your life.
