To create your own specimens, you need a good assortment of clear glass containers. Use canning jars, potion bottles, apothecary jars, wine bottles, or rinse out the spaghetti sauce jar from last night’s dinner. The concept is simple – refill the jars with colored water, add a slimy and creepy specimen, and embellish with labels, paint, and twine.

Wilton makes a Halloween drink-coloring dye set with green, orange, red, and black already mixed for you, available at your local craft store. Hard-boiled eggs, cauliflower chunks, mini skeletons, and light-colored creatures work well in dark colored dyes for the added appeal of not being able to distinguish clear details apart from each specimen.

I found a very inspiring display of potion bottle specimen jars arranged on an antiquated bookshelf with a full tutorial included. Create your own Witches’ Kitchen this Halloween for a unique party theme that will have your guests brewing and bubbling over (with anticipation, I mean. I certainly hope you don’t plan to stuff them into the cauldron…).

Use vintage-style potion bottle labels for added authenticity, such as this beautiful set from the talent behind Love Manor: Bottle Labels.
