How to Turn Your Phone’s Flash into a Black Light / How to Detect Semen on the Go

A black light works by producing UVA light, or ultraviolet light.

Ultraviolet light by itself is above the spectrum of visible light, and cannot be seen. However substances that are emitting light in response to radiation (phosphors) glow in the dark in the presents of a black light.

The glow is created by the special way phosphors use the energy from UV light. When a photon from a UV light hits the phosphorous material, it causes the electrons to get excited and stray farther from the nucleus than they normally would. When the electron falls back to its normal state, some of the energy is lost in the form of heat. When the UV light wave is reflected back to the human eye, it now has less energy, therefore a shorter wavelength. This wavelength is in the range that we can see. The end result being, you cannot see the majority of the light coming from the source, but you can see its reflection off of objects containing phosphors.

Black lights are used in crime scene investigators to identify body fluids – including semen, sweat, saliva and urine. Semen happens to glow the brightest.
Turn your phone to a body fluid tracking tool, and detect semen on the go.

How to Perform an Emergency Tracheotomy

1. Find the indentation between the Adam’s apple and the Cricoid cartilage.

How to Perform an Emergency Tracheotomy on Darth Vader -  Adams apple and Cricoid cartilage
Find the Adam’s apple, then slide your finger down the neck about one inch until you feel another bulge. This is the cricoid cartilage. The indentation between the two is the Cricothyroid membrane, where the incision should be made.

 

2. Make a half-inch horizontal incision about one half inch deep.

Take the razor blade or knife (or a tiny surgical lightsaber) and make a half-inch horizontal incision. The cut should be about an inch deep – there shouldn’t be too much blood.

 

3. Pinch the incision and insert a tube

Pinch the incision open or place your finger inside the slit to open it.
Insert a tube into the incision, roughly an inch deep.
Breathe into the tube with two quick breaths. Pause five seconds, then give one breath every five seconds.
