Give out some paper, ask people to write down the worst sin they can imagine. Have them fold up the paper and put it into the glass. Talk about Calvary. Pour a glass of water dyed with red food colouring over the paper... it disappears. The Blood of Christ cleanses us from all sin.
A very powerful illusion! Instructions and presentation details included.

Comes with three 8.5"x11" sheets of paper, enough for plenty of performances.
