Melting rubber bands may cause you a headache because of the pungent smell it produces. However, melted rubber bands do make an effective adhesive. Once melted, a small nylon or foam paint brush can be used to apply the adhesive to most projects using paper or fabric. Other applications like wood or hard materials will require a little trial and error to see if they work. Melt your rubber bands outside; if at all possible do it over a grill or other outdoor heat source.
Spray a stainless steel or enamel-coated cast iron pot with vegetable oil cooking spray.
Place the rubber bands in the pot.
Place the pot on the stove and set to low heat.
Stir the rubber bands occasionally with a metal or wooden utensil. The rubber bands will melt slowly in the pot.
Wear a face mask while melting the rubber bands if the smell bothers you.
