  • Silly Putty is not intended for use as ear plugs. Known as a "solid liquid", it will not maintain a molded shape. It is composed of a silicone material that becomes softer when exposed to normal body temperature. In addition, changes in atmospheric pressure could force the material to flow deeper into the ear than intended, possibly making contact with the eardrum.
  • Yes, Crayola® Model Magic® pieces can be sealed once they are completely dry. The drying time for Model Magic generally takes 24 hours to dry to the touch and 72 hours (about 3 days) to dry completely.


    How to seal dried Model Magic sculptures:


    1. Apply a thin layer of acrylic varnish to a test sample to check for compatibility before using it on the finished piece.
    2. If the varnish is compatible, apply an even coat over the entire sculpture.
    3. Allow the varnish to dry completely before handling your masterpiece.

    Important Note: Sealing your work will not make it waterproof. Exposure to water and outdoor elements will negatively affect Model Magic, so it is best to display your sculpture indoors.
