Step 3: This shows that the mobile phone camera can detect infrared light-emitting tube.
Try it, really so?
But having iPhone 5, iPhone 5S or iPhone 5C friend we should note, if you take these phones to see infrared emission control, find no matter how you do not see infrared, so please do not be surprised.
