I have friends who are Wiccans. I've always been a skeptic.
Besides crystals, orbs, spells, potions and other things, they have what they call "energy balls".
Here's how they build that "energy"1: they rub their hands together "to open the chakras"2, they spread their hands to about 1 meter appart then slowly move them closer to each other, at one point they feel like there's a ball between their hands which they say is an energy ball. Once they have it they can make it expand, shrink, and disperse it. Experienced practitioners can even dribble with it. Some claim they can see it too.
Before I learned any of those details to prove them wrong (I was REALLY skeptical, I used to make fun of them all the time) I stuck my hand in one and to my surprise it felt tingly.
I experimented some more, I learned to do it myself (it's not hard, follow the description above), and I even asked others to stick their hands in it without explaining what it is and they felt something too. I asked them to try it again doing the same movements making sure I didn't feel anything between my hands (no energy) and they said they didn't feel anything.
What are Wiccan energy balls? Is there a scientific explanation for why you feel like there's something between your hands?
Notes:
- Energy: I really don't know what it is. I know how to make it, I know what people do with it, but I don't know what it is.
- Chakras: They're certain points on the body that interact with energy the best.
