SUMMARY

The discussion centers on reverse engineering a Halloween product designed to mimic pumpkin pulp, which consists of raw loose cotton mixed with an orange-colored gel-like substance. The product is noted for its tackiness, ability to harden within 24 hours, and waterproof properties. Attempts to replicate the product using acrylic medium have failed, as it softens rather than hardens. Participants suggest that the original product's composition may include a combination of a sealer and an acrylic medium, but the exact ingredients remain undisclosed by the retailer.

PREREQUISITES
  • Understanding of acrylic mediums and their properties
  • Knowledge of textile materials, specifically cotton
  • Familiarity with DIY crafting techniques for Halloween props
  • Basic knowledge of chemical properties related to adhesives and sealers
NEXT STEPS
  • Research the properties of various acrylic mediums and their compatibility with cotton
  • Explore DIY recipes for creating stable, waterproof gels for crafting
  • Investigate alternatives to acrylic mediums that provide hardness and waterproofing
  • Learn about the mechanical processes involved in creating stable pulp-like materials
USEFUL FOR

Crafters, DIY enthusiasts, and Halloween prop makers looking to create realistic pumpkin pulp replicas for decorations or theatrical use.

I purchased a product and I'm trying to reverse engineer it. It has raw loose cotton mixed with Orange color and something else. It's mushy and has a tackiness to it and a slick feel.you can pick up this product out of the can and it stays together and doesn't drip, the liquid is thick and has a smell like a acrylic medium ,But when you spread this product on a halloween prop it resembles pumpkin pulp and dries in 24 hours very hard . I can take the product after it dries and it stays hard under water. I tries acrylic medium .....and it just ends up softening, I can't duplicate this product. I took the product and placed it in a bowl of water and moved it around in the water and washed out the color and what ever else was in it to expose the cotton. The oder is not strong its a combination of maybe a sealer and a acrylic medium. But what ever gel material is mixed with cotton it makes it tacky and mushy, any help would be appreciated.

What is the product? Where did you purchase it?
 
It's from a shop that sells a few different halloween products . It's to look like the inside of a pumpkin , the pulp and you spread it on props.... it becomes hard and waterproof .
 
I'm trying to create my own for my own use. I know I can't remake it but I'm trying to make my own product to use on my props.

Have you asked them where they get it or how to make it?
 
Yes, they won't tell me so I decided to try to make it

Maybe put on a disguise and apply for a job there... :wink:
 
Yeah I wish
 
I would like to make my own but tried everything I could think of with no luck. I can get the mushy and stickiness of the product but the hardest and waterproof I can't get.

Somebody might find a suggestion or two if you would say the exact name of the product you bought and tell the ingredients list or description as given on the label.

There are no ingredients listed , it's for halloween to have fake pumpkin pulp. They won't te.l me the ingredients. So I'm trying to make my own and tried a lot of different things .

You could literally make it (cook and mechanical process) pumpkin pulp yourself. Making the pulp should be easy. Not certain what to say about how to make it stable for storing.
