What you get

Sharpen some pencils — and your engineering knowhow — with a pencil sharpener you built yourself! Follow step-by-step DIY instructions to construct the core, add the battery, and wire your mechanism up. Then learn about the invention of pencils, the evolution of sharpener design, and cool engineering features in your sharpener (like the limit switch, which lets the electric circuit know when your pencil is in the sharpener, causing it to automatically switch on)!

My son absolutely loved this! He is drawn to motors, and inventing, so even at 11 years old he was able to build it by himself. I definitely recommend this!

The Electric Pencil Sharpener was a great starter project for me and my son. The directions were very clear and it was a great hands on engineering project.
