At the David Stone lecture, he demoed two tricks which I thought looked pretty decent but unfortunately after buying all his DVD's, I was tapped out! I have looked out for them since but can't see them on sale anywhere. Can anyone tell me where they are available to buy, or even the correct name of the effects.
One was the production of a pool ball from a card case after a spectator has 'randomly' selected a ball (1-13) from 'pool ball cards' I know how this works and can 'obtain'

The other was a colour changing sticky spot on a card, this looked awesome and was very visual. A review of this would be appreciated if anyone has it as I would like to know how well made it is and how long the gimmick would last. If anyone can tell me where to buy this, I will and post a review myself!
Cheers!
