Crayon Heater

In many poor countries and remote areas, crayons are precious to school-age children. Crayon Heater can recycle the crayon fragments and use sunlight to illuminate the head of the convex lens to focus on the pen tube to melt crayon fragments into a new crayon. With Crayon Heater, crayon fragments can be reused effectively and reduce the waste of crayon .
