What you get
Sharpen some pencils — and your engineering knowhow — with a pencil sharpener you built yourself! Follow step-by-step 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)!

Reviews
I like that the projects are always well made with spare parts and easy to follow instructions.
I really loved that it was something you can use regularly, and that it involved electricity. It's also great that it is run by batteries, instead of having to plug it into a socket. I also love that you can store your pencils with it!
It is usable as are most of the eureka crates! And, the kids loved it!
