- How to make a permanent slide of sand. Viewing the sand under the stereo and compound microscope.
Volcanic sand from the Canary Islands (Lanzarote) is observed with a stereo and compound microscope using top-illumination (epi-illumination).

**** PLEASE SUPPORT ! ****
I am fundraising for a new microscope. It will be used to build an archive of images and also for improving the videos of this channel: Please visit the fundraiser: www.gofundme.com/f/microbehunter
Here is a link to the image archive that I intend to expand with the new microscope: www.MicroWorldArchive.org
**** MICROSCOPE RECOMMENDATION ****
I receive many questions on which microscope one should buy. I recommend the following models for amateur microscopy (Affiliate Links to Amazon):
Children’s/Introductory - Swift or National Optical SS110: amzn.to/2WdS4PX
For Amateurs - Swift SW380T (with phototube) or Swift SW380B: amzn.to/3fu7aIY

Your videos are always fascinating
I love the little shell you found there in the sand sample. How fascinating.
I found out recently that a local mountain called Muckish once exported its sand around the world for exceptionally high quality glass manufacture.
More interesting than expected, that's for sure. Would be interesting to have a geologist identify what the types of rocks are and why that is the particular composition that's found on those beaches.
LOVELY VIDEO THANK YOU
Beautiful!!
The sand in your swimsuits may be contaminated a bit from your body microbes
The canaries import sand from the mainland and Africa, because they have so few natural beaches. Their natural beaches usually are very dark and rocky, but tourists prefer light and soft sand, so...
MizzRosenrot But the black sand beaches in Hawaii are famous.
@@TheApoohneicie Well, that's how they do it in the Canaries. Not my fault.
MizzRosenrot I didn’t mean anything by it, just pointing it out. 🙂🍸
@@TheApoohneicie Gotcha! :)
The guy makes looking at sand fascinating
Perhaps washing and thoroughly drying the sand to remove salt and moisture to prevent the grains sticking or clumping would be a good idea for long-term samples.
Subscribed, awesome footage.
Really helpful video as always. I tried this with white beach sand -which was mostly quartz and very impressive under darkfield.
heckkkk a spider came from the underwear haha
You would probably get away with using water-based wood glue thinly spread over a slide as a fixture for the sand because it dries almost clear and would make quite a nice background for the sand with a soft light passing through it, like the stuff you used to make an impression of the stomata underneath the plant leaves. You saw for yourself how difficult it was to remove even from a smooth leave. It may discolour over time, but I will test that out sometime today. I'm going for some volcanic sand today near where I live.
Nice! I'm just getting started. What type of adapter is connecting the camera to the scope? I was thinking of attaching my iPhone with one of the many adapters on the market (don't know which is best). Thanks!
Wooow. Cooking food over an open active 🌋 volcano. I have really seen it all now!
If you illuminate your sand samples with UV light (short or medium wave is best), you'll probably see some grains that fluoresce (glow) a different color. There should possibly be some calcite grains that glow different shades of red/pink/orange, and possibly also some aragonite grains from shells etc that may glow a different color. You may even find some grains that glow green. Perhaps you've already done a video on fluorescent microscopy.
Should have tried Euparal just for the heck of it.
Hey, what kind of microscope would you recommend for a beginner?
I'd like to be able to make pictures.
Can i get a decent microscope that i can film with or rake pictures with for 200(euro)?
Any brand you'd recommend?
I expected to find microbes in the sand.
Can you make an "Ocean water under the microscope" video?
Have you tried illuminating the sample with UV light to see if there are any fluorescent minerals present?
No, as I do not have a UV lamp. But what I might try is blue light illumination, which is also sometimes able to excite some pigments. For some algae this works (chlorophyll).
@@Microbehunter I intend to do more microscopy once I have retired in a couple of months time. I may get an LED UV torch to experiment with. From previous experience most fluorescence is not very bright so longish exposures are needed to record it.
When we see sand under the microscope it doesn't seem so bad having it blown into our sandwiches or onto our ice-cream cone. It doesn't have quite the same appeal in our mouths, though.
Is there an acid test we can do at home to determine the composition of the rock?
How many times he said uh
