Behold: The Lemonade Machine!

A Rube Goldberg machine, for the uninitiated, is a device designed to accomplish a simple task in as many unnecessary, ludicrous steps as possible. The name comes, appropriately enough, from Rube Goldberg, a cartoonist and inventor most famous for his cartoons featuring singularly silly and elaborate machines like the one pictured below.

We’ve posted videos of Rube Goldberg machines in the past, because they’re a perfect example of a mechanical puzzle in action. Only when things happen in a precise order does the machine complete its task.

But it turns out that an old friend of the blog — domino master Lily Hevesh, aka Hevesh5 — is now venturing into the world of Rube Goldberg machines.

And her first attempt was a doozy.

Teaming up with five machine-building YouTubers — essentially, videomakers who specialize in chain-reaction mechanical devices — Lily and the group descended upon an AirBnB in San Diego to build a Rube Goldberg machine that would span the entire house!

The Lemonade Machine, as they call it, travels from room to room, utilizing items commonly found in those rooms (silverware and a teapot in the kitchen, for instance) to construct an epic-length chain reaction with everyday household objects.

The end goal? Pouring a glass of lemonade for each member of the build team.

So, how did they do?

They constructed a real mechanical marvel here. It took three days to build, and another day to execute a complete successful run of all of the machine’s components in a single take. The end result was the largest Rube Goldberg device constructed in the United States this year.

Not only that, but Lily documented the entire process, so you can watch both the construction and the many MANY attempts on Falldown Day to achieve a successful run of The Lemonade Machine.

It’s a mind-blowing feat, combining puzzly skill, creativity, patience, and determination, and there’s no denying that they built something truly unique and pretty cool.

I’m gonna go watch it again.

Citizen Shoutout: Escape 101 Edition!

Welcome to the latest installment of our newest monthly feature on the blog, Citizen Shoutout!

Each edition of Citizen Shoutout is an opportunity to say thank you. It allows us to put the spotlight on folks in the PuzzleNation community who contribute to the world of puzzles and games in a meaningful way.

And in today’s edition, I’d like to highlight a local escape room that is delivering some marvelous puzzly experiences, Escape 101!

Located just off the highway and right by the Danbury Fair Mall in Danbury, Connecticut, Escape 101 offers some of the best, most immersive escape rooms I’ve ever had the pleasure of trying out. Every time the door is shut and the timer starts, you’re guaranteed a fun, challenging, wholly unique solving experience.

You can call or email Escape 101 to reserve a room, or book a room through their website. (It’s always best to do so at least a few days out from your desired date and time, just to give them the best chance to meet your expectations.)

You know you’re in for a quality challenge right away, as your Game Master gives you an opportunity to familiarize yourself with all of the different locks you’ll encounter in your chosen Escape Room. From combination locks and key locks to directional locks, and even a cryptex, they’ve got all sorts of diabolical tricks and challenges awaiting you, so make good use of your time before the room opens.

There’s a quick instructional video, and then you and your group of solvers will decide how many clues you want for your Escape Room.

There are three options:

  • Original: You get three clues and three clues only. Once they’re gone, they’re gone, and you’re on your own.
  • Meet Me Halfway: You get more than three clues, giving you additional chances (at your request) to get past frustrating or confusing stumbling blocks while still giving you a fair chance to escape.
  • Finish the Game: Your Game Master delivers unlimited clues and hints, maximizing your chances of escaping the room within the one hour time limit.

Personally, I like “Meet Me Halfway,” because you can still set the goal of using no more than three clues, but you still have the opportunity to ask for more if you need them. It’s the best of both worlds.

But what about the escape rooms themselves, you ask? Well, I’ve only tackled two of them so far, but I thoroughly enjoyed both experiences.

The easier of the two was The Ice Cream Truck room, wherein you and your group find yourselves in a local park with a simple goal: collect enough money for all of you to hit the ice cream truck before it leaves!

You’ll have to explore your environment, accomplish tasks, and help fellow parkgoers to accomplish your mission.

If you’ve never done an escape room before, I think this is the perfect introductory room. The puzzles are fun and challenging without being overwhelming, and the very environment is soothing, which counteracts the pressure of knowing you’ve only got one hour to escape.

[No pictures of the room, because I didn’t want to spoil any of the surprises for you.]

Of course, if you’re looking for something more challenging, Escape 101 has you covered there as well… with the Doomsday Room.

The Doomsday Room is a combination office/laboratory for the mysterious Dr. Apocalypse. You and your group have snuck into his workspace in the hopes of escaping with a very important bit of information: the date of the end of the world.

But Dr. Apocalypse won’t make it easy. You’ll need to explore the entire space, conduct experiments, show off your observational skills, and more in order to escape in the time allotted. It’s a genuine challenge, but a spectacularly fun one, even if you don’t manage to escape in time.

And if that’s not enough to entice you to visit and test your mettle against one of their escape rooms, we’ve got something special just for local PuzzleNation solvers.

Yes, for the entire month of October, if you make a reservation for a room at Escape 101 and you have one of the PuzzleNation puzzle apps on your phone, you can show it to them at the door and they’ll give you a 10% discount on the entire booking!

That’s right, whether it’s Daily POP Crosswords, Penny Dell Crosswords, Penny Dell Sudoku, or Penny Dell Crosswords Jumbo 1, 2, or 3, being a PuzzleNation solver will give you a discount on a terrific solving experience.

How cool is that?

Be sure to take advantage of this amazing offer, and let us know if you do! We’d love to hear from you!

Thank you for reading our latest Citizen Shoutout. Writing this month’s edition has been great fun.

But what about next month? I’m glad you asked.

As always, I am happy to take suggestions from my fellow puzzlers and PuzzleNationers for individuals, groups, and businesses to highlight in each month’s post.

So, if there’s a puzzler or designer who inspires you, a constructor who challenged you or surprised you with a puzzle, or someone who did something kind in a puzzly way, let us know!

Maybe you have a favorite local game shop / hobby shop where you meet other puzzlers, or that introduced you to a favorite game. Maybe your local library held an event that piqued your puzzly interest.

Maybe you’d like to give a shoutout to an escape room you think others would enjoy (like I did today), or to a puzzly event, like a scavenger hunt, a tournament, or a how-to solve event.

Or maybe, you’d like to put the spotlight on someone who went above and beyond to make a puzzly experience truly memorable.

You can submit your suggestions for the next Citizen Shoutout on Facebook, on Twitter, or in the comments section below. We’d love to hear from you.

A 5-Letter Word Related to Crossword Skills? Try “Music”

A few years ago, I wrote a post discussing the curious intersection of music and puzzles. It centered around several studies about the effects both listening to music and performing music can have on individuals taking tests or solving puzzles.

There were two intriguing takeaways from these studies:

  • Both adults and children perform better on tests, puzzles, and problem-solving exercises when music is involved (ex.: if they listen to music before or during the test).
  • Children who are given music lessons often achieve greater heights in other subjects, including math and sports.

But it didn’t occur to me until much later that the connection between music and crosswords in particular has been in evidence for quite some time.

There are two 7-time champions in the history of the American Crossword Puzzle Tournament: Dan Feyer and Jon Delfin. Think about that. Fourteen out of forty-one ACPT tournaments have been won by one of these men. Practically one out of every three!

And both of them have a musical background as pianists and music directors.

But they’re not the only ones. Constructor Patrick Blindauer, puzzler and actress Whitney Avalon, Lollapuzzoola co-founder Brian Cimmet, and even our own Director of Digital Games Fred Galpern are all musicians.

So what’s the connection between music and crossword puzzles?

No one can say for sure, but there are theories.

In the crossword documentary Wordplay (and quoted from the article linked below), former New York Times Public Editor Daniel Okrent mentioned why he felt that musicians and mathematicians were good fits as crossword solvers:

Their ability to assimilate a lot of coded information instantly. In other words, a piano player like John Delfin, the greatest crossword player of our time, he sits down and he sees three staffs of music and he can instantly play it. He’s taken all those notes and absorbs what they mean, instantaneously. If you have that kind of mind, and you add it to it a wide range of information, and you can spell, you’d be a really great crossword puzzler.

Crossword constructor and psychology professor Arthur Schulman — known for a series of seminars entitled “The Mind of the Puzzler” at the University of Virginia — would agree with that statement. He posited a correlation between word puzzles, math, and music, in that they all involve a quick and intuitive understanding of symbols. It’s about “finding meaning in structure.”

In an interview with the New York Times, Dan Feyer built on this idea, stating that music, math, and puzzles all have pattern recognition in common, quickly recognizing combinations of blanks and spaces and mentally filling in possible answer words, even before reading the clues.

Now, clearly, musical skill and proficiency isn’t required to be a good crossword solver — I’d classify myself as a pretty good solver and I have an almost magical lack of musical talent — but it’s intriguing to ponder how puzzling could easily be wrapped up with a musical bow.

Do you know any other puzzlers with a musical background, or are you a lyrical solver yourself? Let us know in the comments section below! We’d love to hear from you!

A Dollar For Your Thoughts? It’s the Hundred Dollar Puzzle!

That’s right, fellow puzzlers and PuzzleNationers! It’s that time again when we pit our puzzly minds against a fiendish brain teaser and test our mental mettle!

You might’ve seen this brain teaser making the rounds on social media. It’s known as the hundred dollar puzzle, and unlike most brain teasers, this one is less about the puzzle and more about how we got to the solution.

Intrigued? You’re not the only one. Let’s take a look at the brain teaser:

A young man sees a shirt for $97. He borrows $50 from mom and $50 from dad. He buys the shirt and is left with $3 change.

He gives $1 to mom, $1 to dad, and keeps $1 for himself. Now he owes his mom $49 and his dad $49.

$49 + $49 = $98 + his remaining $1 = $99. Where did the other $1 go?

People love brain teasers like this, because at first glance, and even at second glance, the math SEEMS to hold up.

But the real trick to this one is that it’s asking the wrong question. The other dollar didn’t go anywhere.

The problem here is… as soon as he pays his parents back, it’s no longer about one hundred dollars. It’s about ninety-eight dollars.

Let’s look at total borrowings versus borrowings after paying back his parents. The original specs were:

What he owed: $100
What he had: $3 and a $97 dollar shirt.

But the goalposts changed when he paid his parents back a dollar each. (And if he plans to pay the loan off a dollar at a time, it’s going to take FOREVER for them to get their money back.)

What he now owes: $98
What he has: $1 and a $97 dollar shirt.

The math adds up. Your total borrowings go from $100 to $98 dollars, and you spent $97 dollars and put the extra dollar in your pocket.

So the final equation in the brain teaser is flawed. It’s not $49 + $49 = $98 + his remaining $1 = $99. It’s $49 + $49 = $98 = his remaining $1 and his fancy shirt $97.

Sometimes, brain teasers aren’t about crunching numbers, but finding the logical flaw in the puzzle itself.

We hope you enjoyed unraveling the hundred dollar puzzle, and if you have any brain teasers, riddles, or other puzzly suggestions for mental challenges to conquer, let us know in the comment section below! We’d love to hear from you!

The Fine Art of Puzzle Cabinetry

Earlier this year, I wrote a post about puzzle furniture, a small but growing niche of the puzzle world. We explored modular sofa, chair, and desk designs, as well as impressive tables designed by the puzzle wizards at Praktrik.

But what happens when you combine a designer of fiendishly clever puzzle boxes and a furniture designer with an impeccable knack for melding mechanical puzzles and beautiful woodworking?

You get the Wisteria Puzzle Cabinet, an absolute masterpiece that serves as both a stylish cabinet and an incredibly complex puzzle box.

It’s the most beautiful and complicated safe you could ever want, and it would hide in plain sight in your home.

Check out this video detailing some — but I suspect not all — of its secrets, including hidden compartments, an internal elevator, and multi-piece keys that must be uncovered, assembled, and reused:

The puzzly aspects were designed by Robert Yarger (also known as Stickman in the puzzle box world) and the actual cabinet built by Craig Thibodeau, and together, they’ve brought this mind-blowing piece of puzzle art to life.

Granted, the price of an piece like this is pretty steep.

On his website, Thibodeau states that his “latest work exploring mechanical furniture, puzzles and hidden compartments is the most expensive furniture I build due to the highly complex design and fabrication process. These pieces typically start at around $30,000 and go up from there due to the complexity of the internal mechanisms and the variety of hidden details incorporated into the design of these highly unique pieces.”

Although that’s out of my price range, it’s a testament to how much preparation, design, and labor goes into a puzzle as gorgeous and labyrinthine as this cabinet. Even at five figures, it seems well worth the price.

Oh, and if you’re looking for more puzzly furniture, you can also check out the table designs of David Lundell on YouTube, like this magic-themed coffee table:

Now, if you’ll excuse me, I’m going to go check every piece of furniture in my house for secret compartments. You know, just in case.
