Doing a book test twist; does it sound original? Compelling?

This self-post was originally posted to /r/Magic. See more things from Dan's Reddit account.

I’ve got a twist on a book test that I’m hoping to work into a performance in a couple of weeks time (cabaret-size), and I was wondering if anybody’s got any thoughts about it. Specifically: does it sound compelling?

The effect: I’ll be following on from a couple of other mentalist effects and selling this as a “modern” twist on a traditional idea. I’ll ask for a volunteer who has a familiarity with a certain (popular, contemporary, long-running) series of novels, and hand them a Kindle pre-loaded with the entire series, and ask them to inspect it/read any parts of the books to ensure they’re genuine. Meanwhile, three other audience members will collectively supply single-digit numbers which are joined together in an order chosen by the volunteer, to make a page number. The volunteer will then choose their favourite book in the series, turn to that page (you know – the hardest bit so far has been working out how to make a Kindle show page numbers!), and the first sentence will match a prediction that’s been in an envelope on-show since the start. The ebooks can continue to be inspected (and I’ll thoroughly be encouraging the volunteer to show pages to the audience, of course!).

The format has advantages e.g. (a) there’s no way I can see which book was chosen, unlike many similar illusions, (b) I can use a larger “library” than most, and (c) it fits into a patter I have about modernising traditional magic. But I have a few concerns, too.

My concerns: will people assume the Kindle is gimmicked (because it’s hard to see it’s not: people already don’t trust technology!)? What can I do to help the volunteer/audience see that it’s not?

Thanks for any thoughts!

tl;dr: book test but using a whole series of books on a Kindle, inspected by a fan familiar with the series, book chosen by volunteer, page number chosen by audience, first sentence matches on-show prediction. Is it compelling?

Non-transitive Games

Non-transitive dice

Have you ever come across non-transitive dice? The classic set, that you can get in most magic shops, consists of three different-coloured six-sided dice:

There are several variants, but a common one, as discussed by James Grime, involves one die with five “3” sides and one “6” side (described as red below), a second die with three “2” sides and three “5” sides (described as green below), and a third die with one “1” side and five “four” sides (described as blue below).

They’re all fair dice, and – like a normal six-sided dice – they all have an average score of 3.5. But they’ve got an interesting property, which you can use for all kinds of magic tricks and gambling games. Typically: the red die will beat the green die, the green die will beat the blue die, and the blue die will beat the red die! (think Rock, Paper, Scissors…)

If you want to beat your opponent, have them pick a die first. If they pick green, you take red. If they take red, you take blue. If they take blue, you take green. You now have about a 60% chance of getting the highest roll (normally you’d have about a 33% chance of winning, and a 17% chance of a draw, so a 60% chance is significantly better). To make sure that you’ve got the best odds, play “best of 10” or similar: the more times you play, the less-likely you are to be caught out by an unfortunate unlucky streak.

But if that doesn’t bake your noodle enough, try grabbing two sets of nontransitive dice and try again. Now you’ll see that the pattern reverses: the green pair tends to beat the red pair, the red pair tends to beat the blue pair, and the blue pair tends to beat the green pair! (this makes for a great second act to your efforts to fleece somebody of their money in a gambling game: once they’ve worked out how you keep winning, give them the chance to go “double or nothing”, using two dice, and you’ll even offer to choose first!)

The properties of these dice – and of the more-exotic forms, like Oskar van Deventer’s seven-dice set (suitable for playing a game with three players and beating both of your opponents) and like the polyhedral varieties discussed on Wikipedia – intrigue the game theorist and board games designer in me. Could there be the potential for this mechanic to exist in a board game? I’m thinking something with Risk-like combat (dice ‘knock out’ one another from highest to lowest) but with a “dice acquisition” mechanic (so players perform actions, perhaps in an auction format, to acquire dice of particular colours – each with their own strengths and weaknesses among other dice – to support their “hand” of dice). There’s a discussion going on in /r/tabletopgamedesign…

I’ve even written a program (which you’re welcome to download, adapt, and use) to calulate the odds of any combination of any variety of non-transitive dice against one another, or even to help you develop your own non-transitive dice sets.

Penney’s game

A coin being flipped. — Heads or tails? Image courtesy David M. Diaz.

Here’s another non-transitive game for you, but this time: I’ve made it into a real, playable game that you can try out right now. In this game, you and I will each, in turn, predict three consecutive flips of a fair coin – so you might predict “tails, heads, heads”. Then we’ll start flipping a coin, again and again, until one of our sequences comes up. And more often than not, I’ll win.

Play “Penney’s Game”

If you win 10 times (or you lose 20 times, which is more likely!), then I’ll explain how the game works, so you know how I “cheated”. I’ll remind you: the coin flips are fair, and it’s nothing to do with a computer – if we played this game face-to-face, with a real coin, I’d still win. Now go play!

Edinburgh 2012 – Day Two

Our second day at the Edinburgh Fringe brought new opportunities for fun and merriment. Once we finally dragged ourselves from our beds.

First up, we insisted that Matt joined us in watching the show of Young & Strange, a talented pair of magicians we first saw earlier this year, at the Oxford Fringe. Their act wasn’t quite so magical on a second viewing, and some of their tricks wear thin on the closer-inspection made possible by the tiny venue and the orientation of the lights, but they’re still remarkable showmen and real masters of their craft. Matt was invited on stage to assist with a trick involving separating all of the different denominations of currency into twelve numbered envelopes (1p, 2p, 5p, 10p, 20p, 50p, £1, £2, £5, £10, £20, £50). I tell you this because it’ll be relevant in a subsequent blog post. Seriously.

Matt R joins Sam Strange on stage to assist him with a magic trick.

Later, we watched the incredibly disappointing Computer Programmer Extraordinaire, by comedian Raph Shirley. For all of his good ideas (and he certainly had enough of them to fill a 15 minute set, but 45 minutes seemed like far too long), his delivery was sorely lacking. Maybe we went in expecting something that we wouldn’t get – his “geeky” computer programmer persona didn’t really cut it for those of us who were genuine geeky computer programmers in the audience – but even if we put that aside, there weren’t enough laughs in the show to have been worth the time it took to “get there”, even at no cost.

Whisky and cheese tasting at The Whiski Rooms.

Ruth, JTA and I then disappeared off to Whiski Rooms for a “Whisky & Cheese Tasting” event. This was really quite enjoyable, and I was surprised to be able to, under a little guidance (and with the inclination to pay particular attention to the subtler facets of what I was drinking), find entirely new flavours even in whiskies with which I was already familiar. Pairing whiskies with cheeses was also a new experience for me, and – even for somebody like me, who enjoys cheese in moderation but doesn’t have the palate for the full spectrum of cheeses – provided some fascinating opportunities to find new flavours.^*

This – coupled with the drinks we’d already had and those we had later – left us rather tipsy. Although thankfully still nowhere near as drunk as Claire was, here in Edinburgh, when six years ago she did the most embarrassing thing in the world.

Finally, we reconvened with Matt for a dose of Peter Buckley Hill And Some Comedians. I don’t remember his name, but I was particularly impressed with the dry, deadpan delivery of the dutch comedian. If it comes back to me, I’ll come back and write his name in here: ____________________. Look, I’ve left a nice long gap and everything.

^* For anybody who’s interested, the whiskies we tried (and the cheeses they were paired with) were: Tobermory 10 with Keens Cheddar; Jura Superstition with Old Smokey; Bruichladdich 10 with Adrahan; and Bowmore 12 with Dunsyre Blue.

Busy Weekends Part III

As if we hadn’t been busy enough the weekend before last and the one before that, there’s more that I’m only just getting around to blogging! It was only when I thought about writing this up that I realised how much I’d neglected to write about already (and had promised people would be “coming soon”). So, without further ado; here’s what Ruth, JTA and I got up to last weekend.

Aside from our two attempts to conquer the Dunwich Horror (both attempts were failures, although the second was ever so close, ending with Ruth’s character in a one-on-one deathmatch with a Great Old One), our major event was a trip down to London on Saturday. After all, since the move to Earth, London feels like it’s pretty-much on our doorstep: so there’s no excuse not to take in a bit of culture once in a while in the heart of the capital. Of course, when we say culture…

Ye Old Cock Tavern

We started out in Ye Old Cock Tavern on Fleet Street, because – hey – early afternoon is a perfectly good time to start drinking on a weekend. They did some pretty good chips, too, which we picked at as we drank our pints and watched a crowd gather for a wedding at the church up the road, nestled between the old newspaper buildings.

Volupté

Next up was Volupté, a burlesque club with a bi-monthly lunchtime Afternoon Tease. We started with a few fabulously-mixed and ludicrously ornate cocktails: only the first of many. The bar staff are simply entertaining to watch

Aside from the ongoing stream of cocktails (I particularly enjoyed the Porn Star Martini – which I’m seen drinking in the picture above – I don’t even remember what was in it, except that it came with a “shot” of champagne to drink before starting it), Afternoon Tease consisted of:

Drinking champagne and eating finger sandwiches
A guy dressed as Elvis, spinning hula hoops in ways that I didn’t think possible, to a medley of Elvis hits.
An extraordinarily erotic, genuinely tantalising peacock dance from a young lady going by Vicky Butterfly. She later returned for a second, different performance; not quite so arousing but equally mesmerising. That’s her in the picture, above.
Volupté’s special take on traditional tableaux vivants – gateaux vivants: a wonderfully mischievous woman posing behind little more than suspenders and a cake (with a fabulous parody of M&S food adverts gone by).
Scones and tea
A Miss. Rose Thorne, performing a tribute to Doris Day; and I can honestly say that I’ve never before seen a pair of gloves removed with such… deliberate choreography. Very impressive.

By the time we staggered out into the afternoon sun, we were very entertained and quite spiffingly drunk. Volupté gains my recommendation, although I shall have to check the state of my bank account before trifling with their cocktail bar again!

The Golden Hinde

Next up, we made our way over the Thames to visit the replica of the Golden Hinde, the ship in which Sir Francis Drake completed his famous circumnavigation of the globe.

Yeah, it’s just a big boat (and not even that big). Ruth was pleased, though, but she is almost a big a fan of boats as she is for optimised road junctions. Of course, not to break the theme, we stopped for a drink in each of the two nearest bars to the vessel, as well as a snack to give us the energy for the next leg of our adventure, when we whipped out our Oyster cards and zipped down to Hammersmith for…

Penn & Teller

Yes, the Penn & Teller, during their 4-day-only visit to the UK (the first in 15 years), doing their usual mixture of magic and comedy in their in-your-face style, in a spectacular London show. If you’ve gotten this far down the post before you realised how awesome my weekend was, well, what took you so long?

I couldn’t even pick out my favourite part of the show. Perhaps it was one of these:

Teller “drowning” at the end of the first act as part of a card trick (yes, really!) gone wrong.
A whole series of fabulous tricks done with evidently-confused members of the audience (especially the one with the woman they had blindfolded and throwing knives towards Penn, and narrowly missing – it was all done with electromagnets, see?).
Stunning examples of cold-reading done using jokes randomly selected from joke books, with a predictive “hot reading” twist at the end.
The thought-provoking ending, in which Penn (between bouts of fire-eating) asks the audience to think not about how they do what they do, but why, along with some clues related to his experiences as an audience member of various shows.

Sundeep!

By remarkable coincidence, Sundeep and her partner, Ashley, were also at the Apollo to see Penn & Teller! Wandering back from the bar during the intermission we just bumped into her. As she doesn’t blog these days, for the benefit of those who might be wondering: she’s doing well, still on maternity leave and looking after Vanessa, her daughter (who’s looking quite cute in many of the billion or so pictures she carries around with her on her phone), and both are happy and healthy. Ashley – whom we hadn’t met before now – seems nice: he has a certain rugged-but-cute French look and he works for a very worthwhile charity, both of which give him good points in my estimation.

Mexican Tapas

After leaving the show, we were peckish again, so we went around the corner to a cramped but wonderful-smelling Mexican restaurant for a round of Mexican-style tapas, which was delicious. By this point, we were just about ready to settle into a bus for the long but comfortable journey home, when…

Penn & Teller, Again

…wandering back, we spotted a small crowd of people near the Apollo. Wandering over, we discovered that Penn & Teller themselves were hanging out with folks outside the theatre, signing things and answering awkward questions.
Needless to say, we hung around for a few minutes and got the chance to meet the magicians themselves.

Ruth – perhaps as evidenced by her expression in the photo, above – did her usual thing when in the company of a celebrity (as those of you who knew how she behaved around Lloyd Kaufman will know) of becoming a giggling little girl. She also managed to make a fool of herself by mumbling a question about the stage lighting to Teller, to which he didn’t have an answer (not a result of his on-stage muteness, though: he’s certainly happy to talk in person).

Meeting some of the most fabulous (and eccentric) magicians in the world is perhaps the best way to end a night out in London. But there was one more stop on our journey as we worked our way back to a Oxford Tube stop (avoiding the Circle Line, which wasn’t running):

White City

Yeah; perhaps not actually the highlight of the night, but as we were passing, Ruth insisted that we should get one more photo – for Adam‘s sake:

In case your eyes aren’t up to it, or if you’re simply unable to recognise this iconic London landmark, that’s the White City BBC Television Centre in the photo.

We got back to Oxford a full 15 hours after we’d first left: considerably more exhausted, more drunk, and merrily surfing the buzz of all the fabulous things we’d gotten up to over the course of the day. Sunday became very much a day of rest (and recovery) – we’re not as young as we used to be, as I discovered to my horror during my last party-sized jaunt into the capital. Exhaustion aside, however, this was a fantastic day out.

How’ve your weekends been? Not as legendary as mine, I’m sure.
