How to Make Homemade Silly Putty with Glue and Liquid Starch
This stuff stretches and oozes. If you give it a sharp pull, it will break. But if you hold it up, it oozes down.
It’s thicker than slime and perfect for making prints with objects.
We had fun mixing up several different colors of silly putty and making prints with toy cars, dinosaurs, keys, and even Legos! Here’s how to make it.
To make silly putty you will need:
Mix 1/4 cup glue with a few drops of food coloring. We found that adding more than 5-6 drops creates silly putty that stains!
Once it’s well mixed, stir in most of 1/4 cup of liquid starch. When you have stirred as much as you can, it will look like this. Remove it from the bowl and mix with your hands.
Squish and squish until it’s well mixed. It will be stringy at first, but keep going! You can rinse it under a little running water to get rid of the gooey feel.
When it’s finished, it should look like the picture below.
If your slime is too sticky and goopy, mix in more starch. Jonathan’s silly putty especially was too sticky. Every time he played with it, it got all over him. We thought it was just him being 3, but then I “fixed” his silly putty with more starch. No more sticky mess! I simply dipped the whole blob in some starch and then kept squishing.
By far, the boys’ favorite thing to do with their silly putty has been to make imprints with different objects.
