Science Activity: homemade glue

Here's another one of our fun science activities inspired by Science Sparks. I just love their ideas. Almost every activity they come up with seems to be right up our alley.

This week we made our very own glue. I was excited about this for three reasons:
  1. We go through A LOT of glue. 
  2. The ingredients are things we ALWAYS have on hand. 
  3. And, of course, we love science in the kitchen!
So, to begin, you'll need:

  1. milk
  2. white vinegar
  3. baking soda
  4. a pan
  5. water
  6. a strainer
 First we heated 1 1/2 cups of milk in a sauce pan on the stove. Once it was warm, we added 3 teaspoons of vinegar. As we stirred the milk, it began to separate, creating curds (the solid part) and whey (the liquid part). Side note: this reminded me of the nursery rhyme Little Miss Muffet and brought a whole new image to my mind.


Then we used our strainer to strain the curds, which left us with solid little lumps. We put those back into our sauce pan, added a little water along with a Tablespoon of baking soda. Stirred on medium heat until the mixture was a good consistency and....GLUE! We had homemade glue that took less than 5 minutes to make.


Now, C, who was my main helper for this activity, is not a big fan of anything ORDINARY. So, of course, we had to add green food coloring. You could add any color and/or even glitter. This amount of glue almost filled up a 4 oz. white glue (like Elmer's) bottle. Glad we saved those glue bottles.









 This is actually a very functional glue that we used in some crafts right after making it. It works very well.

  1. What a great frugal idea! I will have to try that. I pinned this post. I am a new follower visiting from No Time For Flashcards. Vicky from Mess For Less

  2. Great idea, how long will it keep? Sarah

  3. Hi Sarah, Thanks! Figuring out this homemade glue's shelf life is part of our experiment at the moment. So far, we've been going through it rather quickly with all of our crafting these past couple weeks. It's so easy and quick to make, that we'll probably just make small amounts at a time for now. I'll make a large batch soon, though, so we can see how long it lasts.

  4. Awesome! Thanks for posting this, Megan! We'll have to try it ;) We made homemade playdough a couple of weeks ago. I was surprised how easy it was. I love your post on abiding too! You are so right, my dear friend!

  5. That's so cool! I'll have to try that with my nephew sometime!
