Vampire? Or Penguin?

Your leisurely visit to the zoo will be extra special thanks to this snazzy story time stroller. But wait! Is that…a penguin???

We read Vampenguin by Lucy Ruth Cummins (Atheneum, 2021). When the Dracula family visits the zoo, their first stop is the Penguin House. Everything seems fine until readers discover that the youngest member of the Dracula family has swapped places with a penguin! Penguin is soon enjoying the free zoo tour and stroller ride immensely. But back in the Penguin House, toddler Dracula is causing quite a stir. Can the two secretly switch back without the Dracula family finding out?

Unique and quirky with a hilarious double narrative, we highly recommend this book!

You’ll need:

Let’s start with the penguin, which is a small oatmeal container decorated with construction paper. We did dot stickers eyes and a self-adhesive foam beak, but you can just use markers as well.

Now for the stroller! It’s a little bit technical to construct, but worth it. The kids loved it!

We used a 4.5” X 4.5” x 9” white craft box, but a large tissue box works too! First, cut the top or lid off the box and set it aside for later. Next, cut a large notch in the side of the box, as seen below. This notch ultimately becomes the canopy of your stroller:

Set the box upright (notched end up) and use a box cutter to create two slits in both sides of the top. Insert a chopstick about 2″ into each slit, then secure the chopsticks to the inside of the box with hot glue. It might seem easier to attach the chopsticks to the outside of the box, but we found that they ripped off almost immediately during use.

We also recommend hot gluing the cardboard that was once your box’s lid to the inside of the stroller. Not only does it make it look cleaner, it also safely covers the pointy ends of the chopsticks. Decorate the stroller with color masking tape and/or markers.

The stroller handle is a bubble tea straw bent into thirds and attached to the ends of the chopsticks with color masking tape.

Finally…the wheels! It took us a couple prototypes before we finally hit on the winning design. As it turns out, the front of the stroller has to be slightly elevated in order to keep the penguin from tumbling out AND give it that classic stroller tilt. We taped a basic wheel assembly to the back of the stroller box, then used a scotch tape core to act as the front wheel. Here’s what a completed set up looks like from underneath:

Your stroller is finished and you’re ready to go, be you a penguin or a vampire toddler!

Decalcomania: October 2026

It’s time for more Decalcomania, this time with a spooky October twist, courtesy of Special Collections at Princeton University Library!

We’ll begin with the charming card-playing skeletons you see above. While these bony boys came from a later reproduction, the original artwork, created by out-of-work artist W.F.E. Liardet, was drawn on a Chiswick wall around 1830. This gang is one of 6 vignettes depicting revived recreational activities, including billiards, drafts, cards, dice, toss, and pitch. (GA 2011.00964, Graphic Arts).

This bat doodle, pulled from the journal of John Knowles Lund, surgeon of the British steamer S.S. Cametense, kept as he traveled from Liverpool, England, to Brazil and back in 1902. On December 4th, the bosun brought Lund a vampire bat he found, which he then exterminated with chloroform. (General Manuscripts Miscellaneous Collection, C0140).

Finally this demon, found by library staff member Fabi Garcia, from an 1803 caricature etching entitled “The Funeral Procession of Buonaparte!!” The procession is led by the devil and his fleet of demons, followed by monkey pallbearers, and the Death and the Commander of the Consular Guard as chief mourners. The merry mourners include Switzerland, Germany, Denmark, Spain, and the Pope, among others. (GA 2011.01416, Graphic Arts).


Many thanks to Adrienne Rusinko, Casey Reca, and Fabi Garcia for selecting, researching, and sharing these images from special collections!

Wonka Sugar Science

Last Saturday, good little children gathered outside the gates of Frick Chemistry Laboratory at Princeton University. They all had a special invitation to meet the marvelous creator of all things sugar and science, Mister Willy Wonka!

Well, maybe not the Willy Wonka, but it was a marvelous morning of hands-on science tables followed by an auditorium show that included, among other things, screaming gummy bears (we have footage later in the post!).

The Cotsen Children’s Library was delighted to collaborate once again with the Department of Chemistry and Science Outreach at Princeton University to bring this free education event to the community. It began with hands-on tables provided by the undergraduate and graduate students of Science Outreach at Princeton University:

Back Row (left to right): Catherine Hexter (UAF graduate student), Alexander Luna, John Woo, Ashton Marnik, Jack Langan, Catherine Arbaugh, Joanna Lin, Davis Hobley, Danielle Burke, Paryn Wallace (Associate Director). Front Row (left to right): Sophie Wang, Tanya Zhou, Anna Buretta, Shalini Shankar, Ria Tomar

The event tables featured experiments with density, buoyancy, Pop Rock inflated balloons, the centrifugal force of cotton candy, gum drop candy engineering, sugar crystals under microscopes, and oozy non-Newtonian chocolate rivers!

The thoroughly sugared audience then moved to the auditorium, where the talented Angie Miller from the Department of Chemistry wowed them with not just chemistry, but her sheer enthusiasm for all things science!

Angie demonstrated the scientific method, neon rainbows, giant marshmallow men, candy-colored flames, exploding balloons, a tower of carbon, annnnnd as promised…SCREAMING GUMMY BEARS!


Did the great candy maker himself make an appearace? Why yes, he did, courtesy of Angie’s brother Tom, and his adorable twin boys. Who incredibly, look exactly like Oompa-Loompas.

Let’s see the full costume…

A fantastic time was had! We would like to thank Angie Miller, Department of Chemistry and Paryn Wallace and the students from Science Outreach at Princeton University for a job well done. Hats off to you!
