… that’s the title of an email I sent my wife when I came across this instructables page. She did, and now my BB-8 collection is growing. Thanks Rozenn! You’re awesome. I can’t figure out what Star Wars project I want you to make for me next; it’s too hard to decide.
Here’s the first published remix of my Open Millifluidic Inquiry System (OMIS) made by Thingiverse member Steve Gordon. There are a couple of nice tweaks, including the use of epoxy to keep the support rods in place (a semi-permanent solution, since many epoxies can dissolve in acetone, and since PLA was used in this build, OMIS won’t be permanently damaged by an acetone treatment). Another nice tweak is the use of automatic pipette tips instead of syringe needles to connect the syringes to the millifluidic device. I’ve got some projects that will involve acid in one of the channels, so I need to explore this hack further.
More information about OMIS, such as the bill of materials, build guide, and some ideas on how to use it can be found on my OMIS page.
Andy Brunning over at Compound Interest has created a great infographic to help explain some of the chemistry behind the Flint water crisis. The graphic is below, but I strongly encourage you to take a look at his full article
Andy’s post introduces a lot of concepts that could be incorporated into a Chemistry lecture, making it a potentially valuable resource for connecting what students may find as esoteric concepts to real-life situations. Check out the full article while I jot down some ideas for exam questions….
