You can do three different effects with this trick based on Bob McCallistar's Molly McBubble
EFFECT # 1. A small magic vial is taken from the performer's pocket and shown to the audience. (It may be examined.) The performer tells the audience that its contents have the power to make things appear and disappear right before their very eyes. The cap is removed; revealing a bubble stick attached to the cap. Using the cap as the handle, the performer brings it to his mouth and gently blows a cascade of bubbles from this miniature bubble set. Provoking a giggle or two from the audience, the performer again demonstrates his agility by blowing bubbles again. The magician then reaches out and catches a bubble in his hand saying, "HEY! THAT'S A GOOD ONE!" as the bubble transforms into a beautiful Plexiglas crystal ball in front of the spectator's eyes.
EFFECT # 2. A child is shown how to use the small bubble blower and the magician produces the crystal from the bubble.
EFFECT # 3. A bubble is transformed into a crystal, shown as solid and then bounced on the floor changing into a super ball. This can be given to the assistant as a souvenir.

This is a very effective climax for a production of Cards, or a Card effect like "Six Card Repeat". In effect, the performer tosses a number of loose Cards on to a tray or table. The Cards are covered with a large silk or cloth foulard, which is lifted away to reveal a "Card Castle".
We supply you with the mechanical "Card Castle." The operation of the Castle is very simple. With virtually no skill, the "Card Castle" will appear. This is a fantastic magic trick that can be enjoyed by all. The Jumbo card castle is mad from Jumbo Bicycle cards and is not shown.

COLOR CHANGING DECK by IRV COOK

An eye test is given to a spectator to see if he is color-blind. You go through a deck of cards showing him the fronts and backs. Of course the spectator tells you that the red cards are red, the black cards are black and that all the backs are red. The spectator freely selects a face up card.
He is shown that he has picked the only red card from a blue pack. The question is asked, "How can you play cards with one red card in a blue deck?" A rub on the table and that card also changes to RED! Remember, you started with an entire BLUE deck and end up with an entire RED deck! You can now do any other card trick that can be done with a regular pack of cards.
