What is the difference between Air-Dry Clay and Model Magic?

Crayola Air-Dry Clay hardens to a durable solid and becomes stronger with time. More information about Air-Dry Clay can be found at http://www.crayola.com/things-to-do/how-to-landing/airdry-clay.aspx.

Model Magic remains lightweight and somewhat flexible even when dry. More information about Model Magic can be found online at http://www.crayola.com/things-to-do/how-to-landing/model-magic.aspx.

Both air drying compounds generally take 24 hours to dry to the touch; 72 hours to dry completely. Drying times can be altered by environmental conditions and the size of your piece.
