Crayon Heater / 123

Crayon Heater
Crayon Heater

In many poor countries and remote areas, many children have neither teacher or textbooks, nor
pencils or crayons at school age. Crayons are very precious to them because of limited resources.
Just collect the crayon fragments or the remaining crayon, put them into a crayon heater, and use
sunlight to illuminate the head of the convex lens to focus on the pen tube. Then you can melt the
crayon fragments to make a new crayon.
