The more familiar people are with your props, the more amazed they will be with what you can do with them.
Here's a chart to illustrate some examples:
- Silver and Gold Dragon Box - This is a ridiculous (and imaginary prop) that you could pull a 15 foot palm tree out of and people wouldn't be blown away. It's a prop, you're a magician, they can connect the dots. Method doesn't matter.
- Coin Vanishing Drawer - This gem from kids magic kits has the same effect on everyone else as it did on your parents: That's cute, honey. Prop. Obviously. Method doesn't matter, it's in there somewhere.
- Card tricks - a little more familiar. While everyone has handled cards, they're not genuinely comfortable with them. These tricks are probably more amazing for casino card dealers who play with them every day for hours on end. Most folks are amazed by card tricks, no doubt, but they will never change someone's religion (which should always be your goal).
- I was kidding about the religion bit. I hope you already knew that.
- Money tricks - People always have a little spare change around (whether or not they care to admit it to the man on the corner drinking out of a paper bag). They are familiar with coins, how they feel what they are capable of (and not capable of). Money tricks are knock-out amazing and have the added benefit of mattering in a financial / personal way.
- Borrowed ring (or any other borrowed object) - Always the most amazing since the item is absolutely personal and familiar. You get both the amazement factor from it being SO impossible, to it mattering more than money often times.
Think about these relationships when you're choosing the magic you perform at your next get-together.
