Today we had a field trip in class (I'm so glad those are still a thing!) We toured the local Rockline Industries factory in Springdale, Arkansas. They make all kinds of wipes and coffee filters. It was actually a lot cooler than I had expected, with robot saw blades chopping paper and other awesome stuff. There was also a cool metal detector that they ran all of the product through to make sure no robots were trying to escape the building. The purposes ran metal pieces through it periodically to make sure it was detecting correctly.
I had to wear a security badge, hair net, beard net, protective glasses, and head phones with mic.
