Nice to see you back *waves frantically*

I also had family members trying to convince me about the power of crystals, including electromagnetic filtering and re-energizing of the power of water. Unfortunately not even the scientific approach seems to work to stop the nonsense

It's totally irelevant of course, but light does not always travel in a straight line. There is refraction of course, but also gravitational fields can deflect light. So if your crystal is heavy enough it could deflect light rays and so prevent them reaching you even if it isn't located between you and the source. I wouldn't recommend trying that though as the mass required could (probably would) cause a black hole, and I wouldn't want to have to explain that to the insurance.

Aww! It's nice to be 'back' - although to be honest I never actually left. Just got busy really.

I can sort of understand the thinking. Crystals are so beautiful, so special, they must be good for something!

As indeed they are - good for making watches.

Well, crystal Meth is....

I would suggest hematite, sounds like there are plenty of places near you to be able to get it, if not there are lots of websites where it is available.
It helps to repel electronic smog & other negative influences in the area.

Do crystals work? Well I believe they do, and maybe because of that they work for me. Is it a placebo effect? I don't care. I keep a piece of hematite next to my pc, when i go to bed and i cant sleep I pop a piece of lapis under my pillow & when I know certain people are going to be in at work who really annoy me I keep a piece of ocean jasper in my pocket.
Is the lapis really helping to calm my mind and sort out my insomnia, who cares. I cant sleep cos im stressed out and brain is buzzing with lots of thoughts & idea, maybe having something to focus on helps to provide the peace my brain needs to chill out.
Does the ocean jasper instil patience, again who cares, those certain people dont annoy me half as much as they used to, which makes me a nicer person at work for everyone else.

Aim it between their eyes...it's bound to work.

rap music/swiss "country music"?
batshit crazy ex-girlfriends?
orcs/uruk hai/saruman?
The Local?

thats always an option and previously I did tinker with the idea of pushing them down the stairs

and yes i do think it would work against all those options.
not heard swiss country music, can only imagine it is even worse that other types of that awful dirge

what you need are some crystal skulls:

I have two crystals next to my bed, On the gf side ....if they make her happy then well I leave em there. One looks like kryptonite (sp?) so its pretty cool.

Dont believe they do a damned thing but hey whatever floats your boat.

So long as they're less dense than water.

Its kryptonite man. it can do whatever

Some people hug their teddy bears or request a guardian angel. On the face of it, a piece of rock is no weirder.

Whatever works for you.

Why would you want to repel your own minions? I wouldn't want those stones near me if it would send my minions running away!
