Add 1/2 cup of glue to a bowl.
Mix in 1/2 cup of warm water with 1/2 tsp baking soda.
Add confetti and glitter if desired and mix together.
Add the saline solution to the mixture. Mix quickly until the slime pulls away from sides and bottom of the bowl.
Squeeze a few drops of saline solution (or contact solution if using) on your hands and continue to knead your slime by hand either in the bowl or on a tray.
