Real Pumpkin Slime

Fall isn’t quite over yet! It’s still the season for all things pumpkins! I know a lot of people (including my family) are preparing for the upcoming holidays. Now that Thanksgiving is over, many people will be getting ready for Christmas, Kwanzaa, Hanukkah, and any other holidays that are celebrated around the world during this time! So, before Thanksgiving, I wanted to get in more of my love for autumn. In my home, we were still doing activities related to pumpkins, and we want to share those with you. Here is one of the activities we were able to accomplish before Thanksgiving. Try it out with your family and let me know what you think!

Making slime! What kid doesn’t like making and playing with slime? It’s been a popular science activity among children of all ages. My kids fall right in the category of slime-lovers, and it’s even more fun when they can make their own! My two girls often watch YouTube videos of all kinds of slime being made. They take what they learn and experiment with different recipes and, at times, come up with their own variations.

When I asked if they were interested in making pumpkin slime, their facial expressions told me “Yeah!” Mikayla asked, “Mom, really?” I said, “Yes, Mikayla! Slime with real pumpkin seeds and guts in it!” How cool is that? They never heard of pumpkin slime! I was excited for them and looked forward to when dinner would be over, so we could make it!  

Ayden had a little pumpkin that he saved from his trip to the Pumpkin Fest at Dorney Park, so we used that one little pumpkin for several science activities, including this slime. He was eager to get started. Check it out!

Gather your supplies:

  • ½ cup of Elmer’s clear washable glue
  • ½ cup of water
  • ½ tsp of baking soda
  • 2-3 tbsp of contact solution
  • A little pumpkin (or the seeds and guts saved from a previous pumpkin)
  • Bowl; measuring spoons; measuring cups; spoon for stirring

What to do:

  1. Remove the seeds and guts from your pumpkin and set aside.
  2. In a bowl, stir the glue and water together.
  3. Mix in the pumpkin seeds and guts.
  4. Stir in the baking soda and contact solution. We started with 1 tbsp of contact solution, but found that the consistency was a little too loose and sticky.
  5. After stirring in one more tbsp of contact solution and giving it a good strong stir, the slime started to come together. It is really important to keep stirring because at first, it looks as if it’s not forming.
  6. After giving it a good stir, take it out the bowl and knead it.
  7. When the kids took the slime out of the bowl to knead it, they added a little of the contact solution to their hands to prevent sticking.
  8. The more you knead the slime, the less sticky it becomes.
  9. Enjoy playing with the slime!
  10. After playing with the slime, store it in a zipped sandwich bag or a container with a lid.

Scientific Notes:

The baking soda aids in firming up the slime. The contact solution is the activator to get the slime to the right consistency. Usually, the slime would not have needed the extra tablespoon of solution. If they kept stirring and kneading, it would have been the right consistency. But, it didn’t seem like it was getting there, as in slime they made before. We think because of the food content in the slime, the extra solution was necessary. My kids observed that the consistency of the slime improved, after it set a while. So be patient.

I wasn’t sure how long this slime would last because of the food content. It would probably start to mold after several days. Over the next few days, we observed the pumpkin slime to see if any changes occurred. We noticed that after a few days, the slime remained the same. But, we think the slime will change eventually, perhaps even mold because of the food content. Science is about waiting and observing what will happen over time.

The kids really enjoyed making this pumpkin slime! They thought it was cool to have real pumpkin seeds and guts in it. Mikayla was excited to package up some and share it with her friends at school! Any time your family carves out a pumpkin, save some of the seeds and pumpkin guts to make this one-of-a kind slime! When you make this slime with your family, be sure to share your experience with us!
