Bird Seed Slime


We love making slime — a stretchy, oozy, not-sticky play material that can be played with in a variety of ways, making it one of our favourite sensory activities for kids. We’ve used ours on the light table and to learn the order of the rainbow. Today, we decided to try some Bird Seed Slime!

This bird seed slime is one of our favourite sensory activities for kids! Perfect for learning about birds with kids as part of a bird unit study, or just a rainy day activity.

Bird seed slime has an awesome texture, pebbly yet smooth and stretchy. It is unlike anything your child will have ever played with before and would be a great way to stimulate their senses while discussing and exploring birds.

Slime can require a bit of experimentation and patience, especially if you’re still new to it. If you run into any slime fails, check out this troubleshooting post to help fix your slime.

Before we get to the recipe, I had to tell you that it’s finally here! I wrote The (Ultimate) Slime Book oozing with over 50 pages of stretchable, squishy sensory fun – including a year of seasonal slimes, edible slimes and unique ways to play with slime. Click here to get more details.

You can purchase The Slime Book on Amazon, Book Depository, or at your local bookstore!

Fun at Home With Kids has an awesome tutorial and trouble-shooting guide for making slime. I find that the amount of liquid starch you will need varies each time you make it – whether it’s something in the air or the dilution of the liquid starch, something always makes the exact quantities different. (If you ever run into trouble, leave me a comment or contact me via social media and I’ll get back to you as soon as I can.)

How to make bird seed slime - an awesome sensory play material for kids. Spring sensory play has a new face with this pepply, stretchy slime

I started off just making clear slime and having the children knead it until it became smooth, before encouraging them to add in the bird seeds. You could always present it to your child completely prepared (and this might be less messy) but I liked the added sensory input of experiencing the individual grains and then having the children notice how the slime coated the seeds once they were mixed in.

After stretching, squishing, and flattening the bird seed slime for a while, I added our Backyard Birds Toob to encourage some investigation and discussion of the different birds.

We had previously learned the names of the backyard birds during our “b” is for bird mini unit, so this made for good review. The children also made observations about the physical characteristics of the birds and we talked about the different foods that birds eat and the meaning behind “the early bird gets the worm.”

Sensory activities for kids are a great way to stimulate deep learning and channel their energy, especially on a rainy day.

You could follow this activity up with some backyard bird observing, or a trip to the library to check out some books about birds. (Check out our list of nonfiction bird books for kids before you go!)
