How do you do that trick where someone closes their eyes you do things then say Bloody Mary touch my hand or something like that and they feel something touch their hand and it isn't you?

You will need to have two people to do this

Step one: ask the person who is calling out to Bloody Mary to close their eyes and relax

Step two: ask them two count down from the number you say (start with ten) then stomp when their done

Step three: once they have done that step snap four times in their ears then cross their hands back and forth five times

Step four: repeat step 1-3 nine times, but on step one decrease the number by one each time ( 10 the first time 9 the next, then 8 etc) do this until you get to one

Step five: tell them to repeat after you and say "Bloody Mary, Bloody Mary, raise my hands and play with me"

Their hands should lift, if it does not work try increasing the amount of times you cross you partners arms. This is just a trick, it simulates the muscles moving so your arms raise, but throw in a comment about dark magic to scare your friends!
