Spooky Finger Specimens

Make molds of your own and your family’s fingers to create a creepy jar filled with spooky finger specimens!

Create creepy molds of your fingers and display them in a jar for Halloween with this fun tutorial.

I’m so excited to share this tutorial here today. It’s one of my favorite crafts I’ve ever done. Plus, I was able to get the whole family involved. Sure, casting molds sounds intimidating, but it is really easy. It’s just like they do at the dentist, but making a mold of your fingers is way more comfortable than one of your teeth.

Supplies:

Plaster of Paris 

Alginate 

water

small plastic cups

stir sticks or popsicle sticks

food scale (optional, but very useful)

mason jar

Spooky-Finger-Specimen-7

First you want to create your mold using the alginate and water following the directions on the back of the package. It’s best to measure the alginate and water by weight, if you have a scale. Be sure to work quickly, stirring the ingredients together. Once the mixture turns pink you need to get your fingers in there.

Spooky-Finger-Specimen-5

Using stir sticks or popsicle sticks are best, so you don’t make a mess and can get a well blended mixture. Don’t worry if there are a few lumps.

Spooky-Finger-Specimen-4

At this point I poured the alginate into a plastic cup, tapped the bottom of the cup against the table, and stuck my fingers in the alginate.

Spooky-Finger-Specimen-3

It takes about 3 minutes to firm up. Once the alginate has lost it’s tackiness, wait 30 seconds, then pull your fingers straight out.

Spooky-Finger-Specimen-1

Mix up your plaster of paris with water, 2 parts plaster of paris and 1 part water. Pour into the molds. Tap the bottom against the table to get any air bubbles out. Let sit for 1 – 2 hours to harden. To get the plaster fingers out of the mold, turn the mold upside down and hit the bottom. Then use your fingernails or the tip of a butter knife to grasp the plaster fingers and pull them out. This is a little tricky, but be gentle so you don’t damage the still drying plaster or break the mold. You can get a few uses out of the mold if you are careful with it.

Spooky-Finger-Specimen-6

Display your finger specimens in a mason or apothecary jar, or find another creepy way of showing them off!

Spooky-Finger-Specimen-8

Pin this for later!

Create these fun and creepy molds of your own fingers! Perfect to display for Halloween decor!
