Some kids in my family start losing their milk teeth. 🦷
While we don’t do the tooth fairy 🧚 stuff, I wondered whether there’s any cool kid-friendly experiments 🔬 to do with their deciduous teeth? Like dissolving them in easily available liquids to teach them the importance of brushing, or maybe some material strength tests to show how cool enamel is?
Hit me with some cool ideas, I‘ve got a few teeth to experiment with 😃
Digital microscopes are very affordable. Basic models up to 1000x can be found for 50 USD.
Break one up and look at the different layers under magnification.
Lol, 1000x is such bullshit. It’s hopelessly stacked digital zoom or idiotic lens measurements. 1000x is about the absolute maximum with classic light microscopes and those that can do it are quite expensive. Buy some cheap (stereo)microscope for $100 from some company like amscope (maybe used) and it will be much better and be useful for other stuff.
What do you mean by “useful for other stuff”? It’s still double the investment, what do you gain for this much, realistically, from a purely hobbyist, I’ll check things with my 6yo, PoV? Are we talking genuine trash to good, or more like acceptable to great?
We’re talking gimmick/toy vs basic research tool. You won’t be limited by what’s more or less a low end webcam with a cheap plastic macro zoom lens in front because you’ll have higher quality optics you can use with your eyes. You don’t run the risk of it not working anymore with newer hardware/software. If there’s ever a science project from school or the child is interested in science later on, a proper microscope will still work in 10 or more years, and you’ll be able to upgrade stuff.
You might need to buy used though although the stuff from Amscope and similar companies can be quite cheap while it’s new. Depends on what features you want.
For looking at teeth you’ll want a stereomicroscope which is cool because you can just throw stuff on the stage and look at it like it is and you get a 3D image. It doesn’t have the high magnification of compound microscopes though. Of course if you invest more you can also get good digital microscopes but for $50 it’s not gonna be great.
Can you recommend a model?
I’ve always wanted one of my own and want to show my kid.
The Amscope SE120 is the cheapest one I could find for $60 with 20x zoom but it’s a a kids version. The 306 is more advanced but costs $160 already. For one with continuous zoom you’ll need to spend more, swift has some cheap ones. I bought one from Motic which is was quite expensive but I’m very happy, they also offer cheaper models. It’s always worth checking the market for used premium brands like Zeiss, Nikon, Leica or Olympus because those are usually better than China imports (Amscope, Bresser etc) but it depends on your luck of course. I’d see if I can find a used one by reputable brands, buying a new expensive one was good but I could have saved a lot.
I just noticed that I’m quite high, might change stuff tomorrow
Lol
Eh, seems more or less alright.
You guys are nerds
Imma upvote u but try to be less of a dick in the future 🔬
Hehe sorry just kidding

Yes
Love that one. This definitely goes on the list.
Other nice experiments with a microscope are: looking at the cells of (red) onions, chlorophyll in green leaves, and water from a pond, hairs etc. But I don’t know what kind of magnifying you need. These things are probably not that small.
