Cotsen Ghosties

book cover 3Last Halloween season we took a stroll through our special collections pumpkin patch. Today, we’re looking for ghosts! And we found them in this amazing optical illusion book titled Spectropia; or, Surprising Spectral Illusions. Showing ghosts everywhere, and of any color. Published by J.H. Brown in London in 1864, the book teaches the concept of “the persistency of impressions, and the production of complementary colours on, the retina.”

The illusion is very simple. In the image above, stare at the small black dot by the ghost’s neck for 20-30 seconds. Then look away at a white wall or ceiling. Her ghostly image will appear in your vision, except in different colors (in this case green wreath, blue ghost)!

Scientifically speaking, this is called an afterimage. The color receptors in your eyes work in pairs (red/green, blue/yellow, etc.). When you stare at the drawing and one color fatigues your receptors, the other receptor will step in and dominate for a bit.

The book has a very lengthy description of this concept, as well as viewing instructions that include having the “gaslight turned low.”

Spectropia also has a disclaimer at the beginning: “As an apology for the apparent disregard of taste and fine art in the plates, such figures are selected as best serve the purpose for which they are intended.”

I wish they might have reprinted the disclaimer before THIS image, which honestly is going to haunt me clear through December:

The book concludes with a grand finale image that is not a ghost, but a rainbow! Definitely try this one, because it is so cool to see the colors flip in the afterimage!

Looking more more optical spooky fun? Try making our tabletop Pepper’s Ghost illusion!

Halloween is just around the corner, which means it’s time to head to the pumpkin patch for your favorite festive gourd! Katie and I thought it would be fun to venture into the Cotsen Children’s Library’s special collections vaults and pull a few pumpkin treasures. Enjoy some historic pumpkins from 1900-1990!

One quick note about the pumpkin patch photographed above. It’s from a book titled Halloween (Atheneum, 1993). Written and with photographs selected by Katherine Leiner, it features amazing photographers like Sylvia Plachy, William Wegman, Sally Mann, and Phyllis Galembo. All the royalties and profits were donated to the Pediatric AIDS Foundation. There is a touching introduction to the work of the Pediatric AIDS Foundation by Francesca DeLaurentis, age 10. The book is an incredible collaboration on so many levels.

Home for Halloween

jack o lanternIt might be a smaller, simpler Halloween this year, but that doesn’t mean it has to be any less spirited (oooo bad pun alert!). We decided to do a round up of our Halloween posts for you to peruse, just in case you needed some projects, activities, costumes, or inspiration. But if you are just here to see Katie’s ingenious candy chute, scroll to the end of the post!


Above you see our cute toilet paper roll pumpkin project (bonus…the project is reversible, so no toilet paper wasted), but here’s a variation on it, using a balloon and an LED light. You might try this little lantern project, or go for this spooky votive castle

For those of you looking for projects to do at home with limited materials, we recommend this printable skeleton marionette, or this simple but adorable paperclip skeleton:

You can also try our hanging bat STEAM project, or this adorable ghost box (pair with a story time book and hide and seek game if you’d like)…

Or make your very own shoulder raven! (and meet the REAL Poe raven here):

Looking for a slightly more complicated project with a big WOW factor? Try this tabletop Pepper’s Ghost box, which can be constructed with items in your home, promise!

For your costuming needs, we invite you to check out our thrift store costume challenge, where we basically pulled stuff from an average closet to create literary characters…

If you’d like to keep it all virtual this year, try our online Sherlock Holmes escape room, take a look at some historic book curses, or enjoy our interview with this pumpkin carving master!

And finally…drum roll please…for Halloween 2020, check out Katie’s candy chute for the socially distanced trick or treaters! She constructed it with a 5″ HVAC tube, a pool noodle, and orange and black duct tape. The chute is about 5.5 feet long, which is perfect for distributing goodies to eager ghosts and goblins. I also want to confirm for the world: yes, Katie will be offering packets of Fun Dip this year. Oh YEAH!
