Can You Guess the Secret Word in This Brain Teaser?

On his YouTube channel Mind Your Decisions, Presh Talwalkar shares logic puzzles dealing with geometry, statistics, and algebra. The puzzle below from the former Stanford math and economics student features no numbers, but that doesn’t mean it's easy to figure out.

To solve the brain teaser, you need to guess the secret word based on a few clues. Here’s the set-up: A teacher is leading a class and Albert, Bernard, and Cheryl are his students. He writes the words "cat," "dog," "has," "max," "dim," and "tag" on the board. He distributes one sheet of paper to each of his three students, with each piece containing a different letter from one of the words. He then tells them that together their letters spell one of the words on the board. The students only know their letter, they don’t know anyone else's.

The teacher asks Albert if he knows the secret word. Albert says yes, he does know it. Next, the teacher asks Bernard. After some hesitation, he replies that yes, he knows the secret word as well. Finally, the teacher asks Cheryl if she knows what the word is. She thinks for a moment and says that yes she does. Albert, Bernard, and Cheryl have successfully guessed the secret word. Do you know what it is based on their answers?

Figuring out the word without knowing any of its letters may seem difficult, but it’s not impossible. If you don’t know where to start, think about Albert’s answer and use the process of elimination to rule out some of the letters and words written on the board. Keep in mind that Bernard could only come to his conclusion from Albert’s answer, and Cheryl from Bernard’s.

Still lost? If you haven’t gotten to the bottom of it yet, the correct answer is "dog." When Albert answers that he knows what the right word is based on one letter, you can use that information to narrow down his possible letters to one of the six that are never repeated on the board: c, o, h, s, x, and i. And when Bernard says that he knows too, you can deduce that his list of potential letters is limited to t, g, h, or s. That leaves "cat," "dog," and "has" as the three remaining options. Cheryl’s answer confirms that she has the letter d, which means the secret word is "dog."

This Crafty Bicycle Can Knit a Scarf in 5 Minutes

Knitting can be a time-consuming, meticulous task, but it doesn’t need to be. At least not if you’re George Barratt-Jones. As The Morning News spotted, the Dutch designer recently created a human-powered automated knitting machine that can make a scarf while you wait for your train to arrive.

The Cyclo-Knitter is essentially a bicycle-powered loom. As you pedal a stationary bike, the spinning front wheel powers a knitting machine placed on top of a wooden tower. The freshly knitted fabric descends from the top of the tower as the machine works, lowering your brand-new scarf.

“Imagine it’s the midst of winter,” Barratt-Jones, who founded an online skill-sharing platform called Kraftz, writes of the product on Imgur. “You are cold and bored waiting for your train at the station. This pedal powered machine gets you warm by moving, you are making something while you wait, and in the end, you are left with a free scarf!”

Seems like a pretty good use of your commute down-time, right?

Move Over, MoviePass: AMC Is Launching a $20 Per Month Subscription

Attention serial movie-watchers: There's a new subscription service vying for your attention. Nearly a year after MoviePass brought its fee down to less than $10 a month to see one movie a day, AMC Theatres is rolling out its own monthly plan as an alternative. As Variety reports, you can now see three movies per week at any AMC cinema if you pay $19.95 a month.

The new program, called AMC Stubs A-List, has some clear disadvantages compared to MoviePass. AMC's monthly fee is nearly twice as high and it's good for less than half the amount of movie tickets. And while AMC Stubs A-List only works at AMC locations, MoviePass can be used at pretty much any movie theater that accepts Mastercard.

But once you look at the fine print of both deals, AMC's selling points start to emerge. A subscription through AMC gets you access to films shown in 3D, IMAX, Dolby Cinema, and RealD—none of which are covered by MoviePass. And unlike MoviePass subscribers, people with AMC can watch multiple movies in a single day, watch the same movie more than once, and book tickets in advance online. (That means actually getting to see a big movie on opening weekend before it's been spoiled for you).

There's another reason MoviePass users may have to jump ship: Its critics say its business model is unsustainable. For every movie ticket that's purchased with MoviePass, the company has to pay the full price. That means MoviePass actually loses money as more people sign up.

This has led some people to speculate the service is on its way to collapse, but MoviePass insists it has a strategy to stay afloat. Instead of relying on money from subscriptions, it wants to use the consumer data it has collected from its millions of customers to turn a profit. It's also investing in movies through its MoviePass Ventures arm (the company helped fund the new movie Gotti, which is currently making headlines for its zero percent Rotten Tomatoes rating). But if those plans aren't enough to quiet the hesitations you have about the company, you'll have the chance to make the switch to AMC on June 26.
