STEM challenge - 2 - Technology

This weeks challenge is simple! Your to find a piece of interesting technology and write a post about the piece of technology, descriptions, uses, etc., and don't forget about aesthetics to make it look nice. You can make a model or maybe you've have the actual thing, but you must at least have a photo of it.

Requirements:

- A photo, drawing, model, diagram, or completed version of the piece of technology.

- A description on it

- The basics of how it works

- Must have #StemTechnology anywhere in the post other than the title and the comments.

That's all, it isn't a competition either so no worries there. Have fun!
