nice work. glade many people still see a crystal and feels its life. the perspective hypercube and tetrahedrons are my favorite. have a few devices based on those structures.
So cool ty, I love searching my local river for rocks with crystals on them and inside them. I stumbled upon one by accident and got hooked as I had no clue I could find them in a river here in Pennsylvania where I am is northwest of Philly. To give you a area for geologic reasons. Any idea what of where they come from?
Hii Could you pls answer my question. I'm not able to get the answer for the 2st qn. How does one come with an answer just by looking at the 'macroscopic' structure.?? I thought one had to do X-rays/use microscopes inorder to come with an answer??
I can see having my students watch this as an introduction to crystal systems. Would each marshmallow be an atom and each spaghetti be a bond? I'm just wondering if I could map out the formula for, say an amphibole, using the same method of marshmallows and sticks?
I'd be honored! :) I think it depends on which specific mineral you are using. Sometimes the 'points' (marshmallows) are just one atom, but sometimes they can be a molecule - so you'd just call them ions. I do think you could use the spaghetti as bonds. I decided to keep it simple here and only do the most basic 'unit cell' diagrams of crystal system symmetry because I knew I'd confused myself way too much if I attempted to do any kind of full mineral formula. The hard part is that some mineral structures can be extremely complicated to build like this because even if they fit into the symmetry (like the simple diagrams I built here), they wouldn't necessarily be the same exact shape - they'd fit into a model of that symmetry if you tried to place it into it like a box, but it wouldn't be the same shape. Here's a link to amphibole on mindat.org as an example. www.mindat.org/min-207.html . If you scroll down and look at the 3D diagram of the unit cell, you can see that it has the simple symmetry diagram outlined in black lines, but the crystal structure inside of it is much more complicated. I'm sure you could find a way to make it work though if you wanted to! If you did end up doing this idea, something I thought of that could be a fun bonus is to use different shapes/colors of marshmallows for the different ions, since some ions are larger than others and that affects the crystal structure. If you're also teaching them about Bravais Lattices and Miller indices, you could have them do a similar activity using that information instead! Like building 3D models of those.
Well Done. Question though: Why are the hard cuts between the sentences? No room to process the valuable information, no time to 'inhale'(If I may call it so). Is it a Video-Editor Issue like 'erase all silent parts'? (the Audio-Editor Audacity has this option). Have a nice day
I will get this wrong, but please correct me, I want to learn this very much. The first one (triangular prism) is tetragonal? I say that because I think 2 axes are of equal length, and are all perpendicular? (I'm very unsure of myself). The second one, I guess hexagonal, because of the six-sidedness of all the points. The third, I guess rhombohedral, because it looks like none of the axes are perpendicular, but there are repeating shapes.
it depends on what field of geology you go into! it's difficult to put any job into a 'hard' or 'easy' category because there just is no objectively hard or easy job. Every job has easy parts and hard parts,and a lot of it depends on what kind of person you are and what work you enjoy. If you're in high school and interested in studying geology in college, I suggest taking a class first at school to learn a bit more about the basics and ask questions like this to the professor/teacher - and if you still like the classes and want to continue with a geology degree, I cannot recommend this more - get an internship and/or do a research project! I wish I did an internship during my undergrad before I graduated. It would have helped me immensely. My school required that every student getting a B.S. in Geology had to do at least one research project, so I'm glad that I did that, but it would have been helpful if I did an internship as well, to see the application of geology in a 'real world' setting. good luck to you!
Admit it, you like marshmellows. You didn't say why crystals have different shapes. That is because of their chemistry, the number of electrons the elements have in them, and how the electrons are shared. You can actually tell quite a lot about the elements in crystals by their shapes.
That was a nice refresher. Haven’t thought about crystal systems in many years!
im glad! It was a refresher for me too actually haha, teaching is one of the best ways to learn (or relearn)
Thank you so much for this video, so helpful!
Thank you for sharing all this.. great job
That was awesome, really enjoyed it!
This really helped, I have no idea what it helped with but it definitely did.
Great explanation!
Hello! I'm wanting to learn more about mineralogy and geology as a whole. Do you have any beginner book recommendations on the basics?
nice work. glade many people still see a crystal and feels its life. the perspective hypercube and tetrahedrons are my favorite. have a few devices based on those structures.
Nice video! I was trying to find something to show my kids and this one was the best.
Very helpful! Thank you
That was so great 👏🏾👏🏾
What a great video!
Thank you this is good I needed this
Excellent mam you did my mis concept lots of love ❤
I usually hate other plant and rock lovers houses but I love yours... 😍
Thank you
thank you
Ur best !!
thank you
Thank u
You are way too cool. Thanks for sharing your coolness
says another cool person! haha thank you! ❤

I believe you
Thanks I really appreciate your video, I was looking for an answer and Google kept linking me to crystal medical quackery.
I absolutely love your beautiful hair!
yes nice hair :) bt yes made me think.i always go alone on my explorations a woman with her brain and interest would be a perfect soulmate :)
💜
5:41 in video duration, there's actually 4 rectangles... 2 on the sides and 1 on top and 1 on the bottom. Then the 2 squares.
Oh yeah, forgot to mention great video very informative and learned somethings I never knew about. 👍
Well Done. Question though: Why are the hard cuts between the sentences? No room to process the valuable information, no time to 'inhale'(If I may call it so).
Is it a Video-Editor Issue like 'erase all silent parts'? (the Audio-Editor Audacity has this option).
Have a nice day

Leave your guesses here for what crystal systems you think those shapes belong in... :)
Thank you so much for the advice

That is so helpful with actual 3D models. Now reward yourself and go toast those "stale" marshmallows over the tealight in the background... ,😜
Eating ... stale ... marsh ... mallows 😮😂 ...
