Holy Harbor / life Buoy

Holy Harbor
Holy Harbor

Holy harbor is an “SOS”-shaped life buoy that can absorbing sunlight in the daytime and give off light at night.Its’ large light-emitting area makes it far more visible and easier to be found, in order to increase the victim’s probability of being rescued.

When emergency happens, as soon as the victims press this button,sodium azide (NaN3),ammonium nitrate (NH4NO3),or other materials inside the box will react chemically in no time, liberating a large amount of gas(nitrogen gas or nitrous oxide and water vapor), to shape the SOS.
