Hi everyone - 

We are putting up plexi shields to that clamp on the bench to divide them in half so students can work at opposite ends of the bench, facing each other.  My department chair just suggested that we order some of them in a "thicker plexi" so they can be repurposed as demonstration shields, something I have been advocating for for several years now.  Looking online, the shields I am finding are listed as "thick polycarbonate" (one site specifically said 3/16 in) or "acrylic".  Is there something more specific that you can recommend?  Members of my department really like to push beyond the boundaries of what I consider safe for chemistry demos, so I would love to protect students however I can.  

Thank you,
