How to make glue

Introduction

Running out of glue doesn't have to be a sticky situation, as long as you have a few basic items in your kitchen. This version is even safe for kids to use (though adult supervision is recommended when handling hot liquids or using the stove). Crafts are even more fun when you make your own supplies!

How to Make Edible Glue

Ingredients

Make sure you have everything on hand before you begin. You'll need the following ingredients:

1 tablespoon vinegar
2 tablespoons powdered milk
1/2 tsp baking soda
1/4 cup hot water
· Equipment
Bowl
Spoon
Saucepan (optional)
Cup or Jar
Coffee Filter
Airtight Container

Procedure

Step 1: Curdle the Milk

First you'll need to separate the milk into curds (solids) and whey (liquid). You can do this by adding vinegar.
2. Though it's not necessary, heat the milk on the stove or in the microwave for the best results.About.com: Make Non-Toxic Glue from Milk1
3. Stir the vinegar into the milk.
4. Let the mixture sit for a couple of minutes.PBS Kids: Glue2 The milk will start to separate--you'll know it's ready when the milk appears cloudy.
5. If the milk doesn't seem to be separating, add a little more vinegar.

Step 2: Separate the Liquid and the Solids

Now you'll need to get rid of the whey. A coffee filter works best, but you can also use a paper towel.PBS Kids: Glue2
1. Place a coffee filter over a cup and pour the mixture onto the filter. The whey will start to run into the cup, leaving the curds in the filter.
2. Squeeze the remaining whey through the filter, being careful not to lose any of the curds. If you do, you can strain the whey again.About.com:
3. Scrape the curds into an airtight container.

Step 3: Add Water and Baking Soda

During this step, you can control the consistency of your glue. Adding more water will thin the mixture; adding more baking soda will make it less lumpy.
1. Add hot water and baking soda.
2. Mix until smooth.

Step 4: Use and Store Your Glue

The glue will be somewhat watery. If you're working with thin materials, such as paper, you'll have to be careful not to damage your project. A little bit goes a long way. Follow these tips for best results:
1. Allow your project to sit overnight. At first, this glue will create a weak bond, but it will become quite strong as it dries.
2. Be sure to keep your glue refrigerated in an airtight container so that it will last longer.
