We measured the pulse of even a banana with a smart watch!

All smart watches and wristbands that measure heart rate, including Apple Watch, do not actually need a heart to measure heart rate.

You may notice that it measures your heart rate by attaching your smartwatch or wristband to a banana or toilet paper roll, where it is possible to fool the equipment they have. Those who don’t believe should watch this video, have a good time!
