Penn and Teller should expose their original magic. It shows the world that magicians are, in penn and tellers words "Just a couple of guys who learned to do some cool stuff". For instance, their "Blast Off" routine is amazing until they do it a second time. Where's the magic in that? Its just choreography basically. I dont know, their performance got them where they are now, but I think if they kept their secrets they'd be a lot farther down the road...
I agree with their rights to promote atheism, but in my opinion, religion and magic shouldnt come together. Even if it's just saying what you believe, magic is magic and religion is religion, religious magic would be blasphemous.
farther down the road? you make it sound like they're complete failures. how much more do they need to accomplish. they've had countless tv appearances, several big tv specials. they have toured the world with their magic. they just completed their 4th season of their tv series. they have a headlining show at the RIO in vegas where they perform 6 nights a week. they've released numerous books. penn has his own radio show. what more is there? they are 2 of the biggest names in modern day magic.
every magic trick is pretty much choreography. i don't know why everyone is always so upset with penn and teller "revealing secrets" all the tricks they do reveal, they created the method. i know that they used to "teach" their audience how to palm a card back in the day, i don't know if they still do that, but then a couple of tricks later, they use that palming method to accomplish one of their tricks, and if they are able to fool their audience using the move they just taught them, how much really has been revealed? as for the cups and balls, sure they use clear plastic cups, and sure penn is saying everything that is going on, but if you watch any clip of it, they are going at such a speed that it is impossible to really comprehend what is going on, and that is an art form in itself. No one has supernatural powers, and no one ever has, and they don't want people thinking that they do. they want credit for clever things they come up with, and by letting the audience in on a "few secrets" they are never playing the audience for fools and they can continue to entertain. they have this magic persona of the 'bad boys of magic' and of liars, cheaters, and terrible con artists, but the reality is they are two of the most respectful, ethical and honest performers there are... in my opinion.
they don't expose every magic trick they do, they still have many killer effects that will remain secrets, like their bullet catch, shadows, teller drowning. every trick they perform has meaning behind it, and to me, that makes their magic more real and more entertaining. like when they burn the american flag while it is wrapped up in the bill of rights. it gives substance to the things they are doing.
i'm very biased on my opinion on penn and teller, cause they've been my favorite magicians for many many years, and were the reason for me getting into magic, and i am also a libertarian atheist. as for why magic and religion shouldn't mix... well... i'm just gonna let the obvious jokes go.
