You can feel it on other people's skin too! If they hold a charging phone or tablet while sitting on a bed or somewhere with their feet off the ground (so they aren't themselves grounded) and you keep your feet on the ground and gently stroke their skin with your finger - you will feel them "buzzing" (as long as you're both sweaty enough of course...)
