While planning out our unique Halloween theme last week, I experienced a very curious occurrence. A peculiar little box appeared on my desk – seemingly out of nowhere. As soon as I slid the box open, I realized this was no ordinary trinket, as the little bone laying inside began to slide right out of the box on its own! No matter what I did, I couldn’t seem to get it back in its box and deduced this bone must be possessed. Misplaced and lost, this bone was cursed to stay in this tiny box until it found its ghostly owner.
If you’ve ever wandered through a curiosity shop, chances are good that you’ve stumbled across a particular mysterious vintage magic trick. Neatly packaged up in miniature matchbox form, the King Tut Magic Mummy is an oddity shop classic. The timeless trick uses 2 hidden magnets to eject a mini mummy from its sarcophagus.
For our own curiosity shop theme this year, I recreated the old trick using a special homemade salt dough bone and custom-designed “magic” box. Our puzzling possessed bone combines the same basic principles of magnetism with a simple DIY trick box + bone, for a bizarre bit of black STEAM magic that is guaranteed to mystify and delight!
TIP: Never made salt dough before? My friend Mary Alice of Brainy Beginnings Network was kind enough to share some tips with me when making these, and you can find loads of salt dough info, instructions,

SALT DOUGH RECIPE
Makes enough salt dough for about 10 bones (you only need one for this trick!)
- 1 cup of flour
- 1/2 cup of warm water
- 1/2 cup of salt
You may also want to use a sheet of parchment paper for baking
Possessed Bone STEAM Magic Trick Instructions:
- Download & print our magic box template or grab a small box of a similar size
Print our free template onto watercolor paper or heavy white cardstock. You’ll want your box to be fairly sturdy, so watercolor paper works especially well if you can safely run it through your printer.
You don’t have to use our box template though. If you have a small, thin box laying around (a small perfume box would work well for example) you can use that instead. Our box measures 4.75 inches (length) by 1.5 inches (width) by 1 inch (height) and it’s a perfect size for both the bone and the box.
- Form a bone out of salt dough and bake to harden
Using the salt dough recipe up top, combine the ingredients and form a bone shape that’s about the same size as your box. You can make this easier by laying the box on a sheet of parchment paper and tracing around the box (as we did below). Now you can shape your salt dough bone to fit the traced rectangle. You only need one bone, but the recipe will make about 10, so make a few more just for fun!
yourbones on the parchment-covered baking sheet at 225 degrees Fahrenheit for 1 hour.
Let your bone cool for 15-20 minutes. While still warm, flip to the back and gently scoop out a small shallow circle at one end – roughly the size of your magnet. We’ll be gluing the magnet into this area, so you may want to check and make sure your magnet fits snugly. If your bone is still soft, you can put it back in the oven for another half hour or so, or just let it air dry over time.
- Assemble your magic trick box
While your bones are baking (sounds SO spooky, doesn’t it?!) you can assemble your magic box. If you’re using a small existing box, you can skip this step.
Cut out our free printable template pieces, then assemble with scissors and tape (or a glue stick). You can glue on the same box label we used, or write in your own magic trick name using the blank label template included!
- Hot glue a magnet to the floor of your box tray
The secret to this trick is the magnets! Magnets ATTRACT opposite poles and REPEL like poles, so we’re going to use that principle of magnetism to create the illusion that the bone is pushing the box away. In fact, that’s exactly what it’s doing. The magnet in the bone will repel the magnet in the
box,because we’ll be forcing the opposite poles to face each other.
Make a small dot with a permanent marker or paint dot on either the north or south pole of both magnets. Hot glue one of your magnets to the floor of your box tray – dot facing up.
- Glue the false bottom into your box tray
For added mystery, add a
coupledots of hot glue to the floor of your box tray, then insert the false bottom.
This will cover up the magnet glued to the tray floor, so the “magic” won’t be revealed when the box is opened.
- Hot glue a magnet to the bottom of your bone
Hot glue your second magnet (again, dot side facing up) to the bottom of your salt dough bone.
- Gently push the bone into the box and slide the cover on
Carefully push your bone down into your box (you’ll notice resistance right away!) and slide the cover on.
- Work your magic and try out the trick!
IT’S ALLL-IIIVEEE! Time to amaze friends and family with your STEM-powered magic!
We felt like the salt dough made a perfectly petrified bone, but now that you know the science behind the scare, you can create a possessed ANYTHING!
