First you want to get out a bowl and pour your glue into the bowl.
Next you want to add in your green food gel coloring. You won't need much, just a tiny bit goes a long way, unless you want your slime to be a darker green.
Now you can add in the baking soda and start mixing.
The next part will be to add in the saline solution. Now for this part, just keep adding some little by little until your slime starts to form. Keep adding a bit until it is now longer sticky.
