Since I was so bad at drawing 3d structures for molecular geometries, I looked for something that would help students visualize them. I found the perfect free combination 😃 Tinkercad to create & Sketchfab to display. Since I'm retired, hope others can use them #ChemSky

Damn! This would have been so helpful for the chromatography sections of my reports 😀
This is Awesome @chemixapp.bsky.social

Whether you need a diagram showcasing chromatography, SPE, mixtures or separation, our multi-colour liquid feature will help. You can control how many layers, which colours and how much the colours blend together.

Not sure when @autodeskedu.bsky.social Tinkercad removed the limit on the number of elements allowed on screen for Codeblocks but just coded my Energy Levels project. After seeing how they coded Light Up challenge, hadn't used the new blocks, & saw the inspector controls.

All done! 😊
Very cool set. I like all the science & engineering being shown on it. Still disappointed they covered up the spectrum under section of book. Luckily they provided doubles of the color tiles so made my own to place in front 🙂 The radium tile is so cool. It freaking glows in the dark! 😱

Time to work on a new LEGO set and listen to Sting 😊
Had to get this one... It's got a freaking atom and Marie Curie 😱

Chemix isn't just for chemistry, try us for biology set ups too. Anything we're missing? Let us know.

Still trying to organize all these books since I picked up a few more when I visited @vortexbooksncomics.bsky.social 😊
Think most of @briankeene.bsky.social books are organized along with @marysangiovanni.bsky.social, @somercanon.bsky.social @mattwildasin.bsky.social, @kozeniewski.bsky.social,...

AI can do some impressive things, but drawing accurate lab diagrams isn't yet one of them... That's not a Liebig condenser. Equipment is mislabelled. And what's that contraption on the right?
Maybe best to stick with Chemix for now 😉. #MadeWithChemix #EduSky #ChemSky

That was a nice 2620 mile road trip.
Thanks again to @marysangiovanni.bsky.social and @briankeene.bsky.social for making my visit to @vortexbooksncomics.bsky.social Awesome! 😊 Can't believe I got to hang out with y'all. I might have been fanboying a little bit 😆

Thanks @marysangiovanni.bsky.social for signing my books! I'll try to see if I get you to sign Thrall in 7 years for the fourth autograph 😁
If I remember correctly the first one was from WHC 2011, the second one was @killerconaustin.bsky.social 2018 and today's was @vortexbooksncomics.bsky.social 😊
