The only way to actually check is to try it yourself.

It is very real me and 2 of my friends did it about a year ago now and that shit moved my finger on its own i didnt move it ... The spirit started off by saying hello than we all started freaking out than we asked foe his or her name and he spelled out Ronald and than i almost shit myself and we asking when he died and he spelled out 1904 and than after that one of my friends got to scared and left the house and than he stopped replying to us so yeah its very real haha i recommend doing it when your older like 16+

I've tried one before so I believe they're real. When the 'spirit' started moving the cup the temperature in the room dropped a lot lower to the point where I was kind of shivering.

Obviously they aren't real. The companies who make them are sitting back laughing at the people who buy them.

I have a few times, I don't really believe in paranormal activities, I'd think there is a logical explanation for everything whether that be something we can or cannot comprehend, there still is an explanation.

ive used an ouija board on several occasions and i only use them to scare my friends..
they arent real and dont contact the dead, its a toy made by hasbro and many illusionists, mentalists etc have revealed it to be fake

I love the whole idea of them!
They scare me far to much and I'd never personally try one but I do believe they are real and it would be a cool thing to do once in my life!
