It is a reliable bit of perform, Bodhi, well accomplished...but I'm struggling to check out who It is aimed toward? The chemistry primer is clear and beneficial for intrigued novices, but probably completely unwanted for any individual who previously contains a hotplate, stirrer-bar and many a person litre flasks lying about...? I'm sure you stated it isn't really designed for novices, but they're prone to be drawn additional to it, and It is likely deceptive/demotivating to give any novices looking through it the impact Having said that items are needed for any extraction.
