The Ghost Post

ghostbustersIt’s a special week for hoots and haunts, so we’re delving into the blog archive to deliver our most ghostly posties for your Halloween celebrations!

We’ll begin with the haunting of this prime piece of story time real estate. After reading I’m Not Afraid of this Haunted House (Carolrhoda Books, 2005), kids built a “Haunted House Kit” then headed into House 13 to bust some ghosts:

If you’re looking for a delightful book to share this Halloween season, we highly recommend Gustavo the Shy Ghost (Candlewick, 2020). We paired our reading with a glow lanterns and gallery ghosts. And if you’d like to visit the studio of the book’s author and illustrator, Flavia Z. Drago, you’ll find that here!

Want to get a little more sophisticated? Try building our tabletop Pepper’s Ghost illusion.  We also tried a more basic variation of the illusion using a phone and a plastic drink lid!

HAPPY HALLOWEEN!

Gone Was Any Trace of You

Need to keep things like a secret? Well tortured poets, we have the perfect pen for you! Katie tested the Elemental Ink Pen by The Shop of Many Things. That’s right. You’ll have your own blank space, baby. And you’ll write your name. Take it away, Katie!


I am constantly searching for clever ways to develop clues for future Cotsen escape rooms. The Shop of Many Things Elemental Ink pens (a 3 pack is $20) definitely sounded like they would be perfect for a riddle mastermind.

According to the packaging, the elemental ink disappears when exposed to heat (104°F or 40°C) and reappears when cold (14°F or -10°C). I used my gas burner stove and a lighter as the heat source, and ice packs and my freezer for the cold. Other heat ideas include a light bulb, steam from boiling water, or an iron. Dry ice is recommended for cold. And if you are fortunate enough to have access to a laboratory with liquid nitrogen, that would be ideal!

Right out of the bag, all three pens didn’t work. I wasn’t sure if it was user error or lack of ink, but I was rightfully disappointed. It took a few minutes of scribbling lines and circles on a piece of scrap paper before the pens miraculously came back to writing life. Armed with a clever notepad (courtesy of Pop Cult Paper), I created a list of tasks:

The ink couldn’t take the heat over the stove burner and it disappeared immediately. In fact, the first time it happened, I gasped out loud. It was pure magic!


I also used a lighter both in front of and behind the paper with the same result. The lighter did leave burn marks on the back of the paper, so please be careful. We don’t want your paper to go down in flames!

It took longer for the ink to return in the cold. Simply placing the paper on an ice pack didn’t work. At all. I tried putting it between two ice packs. No go. The ink really wasn’t legible until I put the paper in the freezer where the air was cold and left it inside for around five minutes.

The Shop of Many Things claims the ink will disappear and reappear multiple times without fading, so I put that claim to the test. I went through the heat and cold process five times with the note on the left and just once with the paper on the right. Dear reader, you be the judge.

I also tested regular ink and the elemental ink to compare any differences. The elemental ink disappeared and reappeared, as expected. Absolutely nothing happened to the regular ink, also as expected.So you could write a message in regular and elemental ink, heat it up, and watch part of your message disappear! So go on, draw those hearts in the byline.

Overall, the Elemental Ink pens are a fun new addition to my escape room tool box. The ink instantly fading away using a heat source is highly entertaining, but I feel it is too arduous and takes too long for the ink to return in the cold. The bigger question is… will the Elemental Ink pens be used in an upcoming escape room? That hot topic inquiry stays cool with me.

The Young Federalist

It’s not everyday you get to hold history in your hands! But when Princeton University sophomore Abigail Readlinger gifted us a copy of her children’s novel, I just had to facilitate a connection between her love of American history and our special collections. Later, I asked Abigail to write about her experience and share the inspiration for her charming book…


Firestone Library’s Special Collections gave me the chance to travel through time. Among its vast array of original documents and fundamental texts is Alexander Hamilton’s very own copy of The Federalist Papers. Writing in the late 1780’s, Hamilton—along with John Jay and James Madison—drafted this series of eighty-five essays in hopes to encourage the ratification of the new Constitution. These Federalist Papers, as evidenced by their substantial contribution to the adoption of our government, are ones of profound and utmost importance. They reveal the nature of American political thought and a corresponding guide by which we ought to live by.

I myself am somewhat obsessed when it comes to The Federalist Papers. Forced to read them during my freshman year of high school, I became immediately attached. I had always loved American history, and The Federalist Papers seemed to transport me directly into the minds of our great Founding Fathers. Desperately bored during the pandemic, but armed with my love for The Federalist Papers, I began to write what is now a published children’s book: The Young Federalists.

The story follows the journey of the Kennedy siblings—Reagan, AJ, and Dolley—as they travel through time, meet Alexander Hamilton and discuss (over a cup of tea!) the importance of Federalist No.1. Just as Hamilton endeavored to inspire his generation through his writing, so also do I hope to inspire mine. The value of the American way is timeless—from then to now, for old and for young.

So when I heard Hamilton’s personal copy of The Federalist Papers just so happened to be located in my own university’s special collections, I jumped at the opportunity to see it.

I still cannot quite articulate the feeling of flipping through the pages of a book both so informative in my life and belonging to one of my most beloved heroes. In 2024, author of The Young Federalists, I was holding the same book that Alexander Hamilton, author of The Federalist Papers, once held over two hundred years earlier.

Just like the characters in my book, I was having my own time travel adventure. Visiting special collections, peering over the handwritten scribblings of Hamilton’s notes, and experiencing history hands on, has been by far one of my favorite Princeton experiences. There is so much to explore in our university’s incredible collection, and to have had this opportunity has really been beyond my wildest dreams.
