There are some spells and magick involved, but I mean, it's nothing like Harry Potter. It's more about the kind of energy you put off. For example, what little practicing we do is reading tarot cards for ourselves (which we take with a grain of salt) and when a place feels wrong or "evil" we will cleanse the area with incense and salt to ward off evil (it seems to work). We occasionally try to cast spells to improve things for people (never to hurt people or do anything Harry Potter-like), but it doesn't usually seem to have any effect on things. That's pretty much the extent of it for us.
However, others focus more on the "magick" part and spell-casting, rather than the basics, and some of them get rather weird about it. Technically Wiccans are called witches, but there's not as much practicing of magick in my family.
Personally, I think most of what magick I have experienced will someday be scientifically explained (probably won't be called magick then) as none of it involves flashing lights or transformation or flying on brooms or any of that, and instead is mostly the energy/atmoshpere/that kind of thing. It's probably got a logical explanation somewhere. And in general, for those who are familiar with Star Wars, I feel that what we'd call magick is more akin to the Force, but obviously without the jedi/sith powers, sadly. It's just an energy that can be influenced, I guess.
And obviously none of you have to believe any of that, just further explanation from my experience for anyone who is curious.
