I Never used one.
You can make one. Thats what I did. I would look up saftey on using a weegee board though. The spirits can get out and kill,possess,hauntyou ect.
For a minute there, I thought you were wanting us to wear protective goggles and lab coats.
Sprits do not exist, though. I imagine it's only people's imagination that drives them to do stuff under the illusion of being possessed. If spirits wanted to contact us, surely they'd have more to say than relying on an obscure game of Scrabble.
