The research is strictly we come across our various homes and roadsides are heavy based on designing a mini skewer that will comply with and thus, are not easily carried around.

This project involves the fabrication, which is charcoal is also a danger to the environment in that modeling and construction of a mini skewer with a the process of even acquiring the charcoal promotes specification regarding strength, material and cost.
