Secret Purposes Behind Common Items That Will Blow Your Mind

#49: Camera Magic

Your smartphone camera is more powerful than you might think. It can actually detect infrared light, something the human eye can’t see. You can test this out using a remote control. Just press a button on the remote and point it at your phone’s camera—you’ll likely see a flashing light appear on the screen.

This trick works because smartphone cameras are sensitive to light wavelengths beyond human vision. While not exactly practical, it’s a fun experiment that reveals how advanced your tiny camera lens really is. Try it next time you’re bored—it’s science and tech in your pocket.
