How do you make silly putty with baking soda?

You can't make silly putty with baking soda alone! Silly putty is made with a combination of ingredients that create its unique texture. Here's a basic recipe for homemade silly putty that doesn't use baking soda:

Ingredients:

* 1 cup white school glue

* 1/2 cup liquid starch

* Food coloring (optional)

Instructions:

1. Combine the glue and liquid starch: In a large bowl, pour the glue and liquid starch.

2. Mix well: Use a spoon or spatula to thoroughly combine the glue and starch until everything is well blended.

3. Add food coloring: If you want colored putty, add a few drops of food coloring at this stage and mix until evenly distributed.

4. Knead: Once the mixture starts to come together, transfer it to a lightly floured surface and knead it for about 5 minutes until it forms a smooth, bouncy ball.

5. Store: Store your silly putty in an airtight container to keep it fresh.

Important notes:

* Liquid starch: This is the key ingredient that makes silly putty work. You can find it in the laundry aisle of most grocery stores.

* Consistency: The putty should be soft but firm enough to bounce and stretch. If it's too sticky, add a little more starch. If it's too dry, add a few drops of glue.

* Cleanup: Silly putty can be a bit messy, so have a damp cloth or paper towels handy for cleaning up spills.
