Thanks for plastic recycling edit and the user box

I loved the dihydrogen monoxide userbox! When I taught freshmen biology labs, I showed the students the MSDS of ultra-pure water, in an attempt to get them to use their heads better than federal regulators! Your userbox brought back many memories! NaCl MSDS was another of my faves. DennisPietras (talk) 02:21, 17 March 2017 (UTC)[reply]
