Practical Joke - Fake Xray Glasses

X-ray Glasses can see through some type of materials making it possible to see through clothes that in the same condition cannot be seen by the naked eye. The theory behind it is simple. Under normal light, the visible and infra red lights can pass through some type of material covering an object and are reflected by the object's surface. The reflected visible light is too strong and saturated to see. Therefore the covered object surface cannot be visible using naked eyes. However, if the reflected visible light is filtered out and only the reflected infra red and the required light is captured using special made sensitive cameras inside the Glasses, the covered object surface will be visible. Some materials completely block the naked eye from seeing through it.
