This is not the first Pepper’s Ghost illusion to appear on Pop Goes the Page. Back in 2020, we posted a kid-friendly version featuring a spirited fox. The illusion is basically a reflection trick, but it’s very effective when done right!
You’ll need:
- A clear plastic drink container lid
- Paper (heavier paper or thin cardboard works best)
- A small section of clear plastic (like the lid of a food container)
- Scissors and pencil for construction
- Cell phone
The project was originally designed and posted by artist Joshua Ellingson on his Instagram. First, wash a clear plastic drink lid. Then cut a half circle template out of paper. When you have a half circle that correctly fits at a 45 degree angle inside your cup lid, trace the paper template onto a piece of clear plastic. We used an acrylic gift box, but plastic food containers work great too. Tape the plastic half circle inside the cup lid. The hardest part is getting that 45 degree angle just right. I made about 4 templates before I finally nailed it. Here’s my finished cup with the plastic half circle:
Head to YouTube for a Pepper’s Ghost illusion on a black background. We tried a couple different ones, but had the most success with this hummingbird. Cue up the video on your phone, maximize it to full screen, and lay the phone on a tabletop. Place the cup lid on top. Finally, roll the video and turn off the lights! Your object will appear to float inside the cup lid! It’s really quite remarkable.
The original designer, Joshua Ellingson, also made a GIANT version of this craft with a thrift store bubble chair and his flat screen television. It’s a must see! And Disney’s Haunted Mansion famously employs this illusion, including an entire ballroom of ghosts!
Last Halloween season we took a stroll through our special collections 
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!
The churchyard is part of the Old Dutch Church of Sleepy Hollow, which was constructed in the 17th century. Featured in Irving’s short story, it’s one of the of the oldest churches in New York State.
From the church, we headed down to the FAMOUS BRIDGE. Which, as it turns out, is the “is the most popular destination in Sleepy Hollow that doesn’t exist.” Because the simple 1700s wooden bridge that inspired Irving has long since disintegrated (you can read a little more bridge history 
The bridge is located in a pretty major intersection with a gas station nearby. So it’s almost a blink-and-you’ll-miss-it historical literary moment. Here’s the bridge as it stands today…
Not far from the bridge is the town’s official statue, depicting Ichabod’s fatal race home. This was a bit of a surprise too. I expected something more traditional. But I like the metal layers on this interpretation – they’re almost like a paper cut silhouettes. Unveiled Halloween 2006, the statue was designed by artist 
We also got an unexpected surprise at the nearby Philipse Manor train station, which operates on the Metro-North Railroad’s Hudson Line. The station’s pedestrian bridge had really cool stained glass windows…
And check out the VIEW of the Hudson River on the other side!
At this point, we were getting hungry, so we headed over to Tarrytown for some bites. Main Street was charming, walk-able, and there were plenty of eateries to chose from.
One other building of note is the historic Tarrytown Music Hall, a 136 year-old 
The sun was starting to set as we headed back to New Jersey with haunted places still on our minds. This Halloween, when I revisit Irving’s tale, I’ll actually be able to say that I’ve walked through the cemetery, stood next to the church, and crossed the bridge! How awesome is that?
The L shape box is consists of two sections: a “forest section” and a “ghost section.”
Next, cut a small square (approximately 1.75″ x 1.75″) in the side of the box that faces the forest section. This is your viewfinder.
In the book, Arlo gazes through a slipknot, a loop of rope or lacing that allows him to see and travel multidimensionally. In order to replicate that rounded view, we slid a 2.25″ piece of toilet paper tube into the viewfinder as well.
Now draw a backdrop for the wall opposite the viewfinder. I had the kids decorate a pre-cut piece of paper or cardboard, then we glued it to the inside of the box.
Next, sketch a ghost on a piece of white card stock. Here’s my tribute to Fox, a spirit from the book (and my favorite character):
Tape the ghost in the ghost section of the Pepper’s Ghost box. Though you will probably need to do a little adjusting on the exact placement, try to arrange the ghost in the center of the section. I found this gave the best results.
Now for the magic! A Pepper’s Ghost illusion is essentially a reflection. For this model, the reflection is caused by a piece of glass or clear polystyrene set at a 45 degree angle in the junction of the L shaped box.
During my initial test, I used a piece of glass from a 4″ x 6″ picture frame. However, I was a little uncomfortable giving multiple 6-8 year-old kids pieces of glass to take home. Luckily, I found clear polystyrene sheets on Amazon (a set of ten, 8″ x 10″ sheets cost $15). Polystyrene is plastic, lighter weight, doesn’t shatter, and you can cut it down to size with a box cutter or scissors. Testing revealed that the reflection illusion works just as well with polystyrene as glass. Yay!
Then hinge a second square of cardboard over the ghost section. It’s important that this flap open and close. With the flap closed, the ghost will not appear through the viewfinder. But when you lift the flap, the ghost section will illuminate, causing a reflection to appear.
Ready to see the illusion in action? Close the flap and peer through the viewfinder. Keep gazing through the viewfinder, then lift the flap over the ghost section. Your ghost will magically appear! I also encouraged kids to stick their hands in the forest section and try to grab the ghost. Their fingers passed right through it, of course!
