- a bag that opens or closes
- two stones one blue one red.
Put the stones in the bag now think of a question. Now that you have the question, say;
Spirit of knowledge, Guide my hand to the correct answer. Should I do the this/working of ( say what you plan to do) or not?
Blue means no, red means yes.
Now draw out a stone. Which ever color you get decides yes or no.
