Sticky Slime

When you first make slime it will be sticky. That is just the nature of slime. Resist the urge to toss it or believe that you’ve failed. Stick with the kneading process. By continuing to mix your slime will slowly start to become less sticky.

I’ve tested this recipe lots of times and have produced awesome slime every time. No need to add any more of any ingredient, Just keep mixing!! Think of Dori from Finding Nemo: “Just keeping Mixing”

What Kind of Pumpkin Seeds To Use

You can use any type of pumpkin seeds you are comfortable letting your child play with. I used dried unsalted seeds.

How to Activate Your Slime

This is very important: To activate your slime you will need contact lens solution. Not every contact solution is created equal, at least when it comes to activating your slime. Make sure to purchase slime that has boric acid and sodium borate as the main ingredients. The brand that I like to use is Renu Fresh. If you use a contact lens solution without these ingredients your slime will not work.

How To Make Pumpkin Guts Slime

  1. Empty the entire bottle of Elmer’s clear glue into a bowl. To make a good amount of slime you will need the entire bottle. To get the residue, use a box cutter to cut open the top of the bottle and use a craft stick to scrap out as much of the glue as you can.
  2. Add 1/2 cup of warm water and mix.
  3. Next, add 1/2 teaspoon of baking soda and mix thoroughly with the glue and water solution.
  4. Add some orange food coloring.
  5. Add 1 tablespoon of contact lens. Mix throughly. You slime will start to form at this point but it will be sticky.
  6. Add some pumpkin seeds. You can add a little now and then add more later on!
  7. Keep mixing until the slime becomes less sticky. Remember the slime will be very sticky at first, that is totally normal, keep mixing until the stickiness decreases.
  8. Start kneading with your hands to continue to chemical reaction and to reduce the stickiness. Resist the urge to add anymore contact lens solution or other ingredients. Your slime will slowly become less sticky as you knead it with your hands.

How to Store Your Pumpkin Guts Slime

Store your slime in an airtight container. It will last about a week. I like to store our slime in a ziplock Make sure to remove as much air as you can to ensure that the slime lasts as long as possible.

TV Show: Curious Crafting

I’m so excited to finally share my new crafting TV show Curious Crafting which launched July 1 at on TVOkids and TVOkids YouTube!

This show is all about fun and easy crafts for toddlers and preschoolers. 

Set in the ultimate crafting space, Curious Crafting is a short form pre-school age series about the joy of making crafts. I lead a rotating cast of adorable little preschoolers (including my own) making magic out of common household objects.

In each episode we transform recycled items into magical crafts like a milk carton school bus, paper bag puppet or cotton pad turtle. The crafters learn and laugh their way through each activity while demonstrating what their young imaginations can create. 

Curious Crafting shares the adventure and joy of making art with takeaway lessons for creating crafts at home.
