Brilliant idea.. What about using a Nano/micro submersible pump., although might need to find larger necked Baubles to fit them inside.. or create Snowglobes where the pump can be hidden in the scenery !!
Really nice! You can use that magnetic pill shape that some auto mix coffee cups use. Just use a magnet under the glass and put a small metal stick I think will do the job. Great job tho, love it
Thank you! Good idea, I also tried this thinking I could make an interesting lamp, however I found the that it resulted in a "dull" effect. Since the effect relies on reflecting light it is better to have an external light source than an internal one
I second the mineral oil comment, it's non-conductive and is used often in liquid cooled PC systems. It would be interested to try and edge lit laser etched plexiglass container that had the fluid behind it. You could also try less rheoscopic fluid in mineral oil to make a more wispy but still visible lamp.
If you wanted to keep the water for low viscosity, you could opt for a magnetic stirrer method. Plenty of DIY options via google. You could leverage the micro stepper motors mentioned, to keep the size down and either on the backside or bottom you could 3d print a small housing for it that wouldn’t look bad. Honesty I think the simplest method however is still mineral oil. It mixed well and your mean time on the motor should be ready no shorter then it was outside of it.
Nice video dude. Someone also suggested thermal convection, but have you considered Making your own base that uses the principal that a chemical stirrer does. It uses a motor in a base to spin a magnet at the base of a beaker or other glassware. Might be a solution (pun intended) to avoid submerging your electronics.
Great Video! This is a REALLY Cool project and something I can Totaly do with my son this year in time for Christmas! I also think I will be adding an LED to the mix somehow, lol (kinda my "thing") and maybe even do this with a slightly larger ornament... Wish e luck, lol. :)
Steppers should last longer immersed, there are no brushes to corrode. And you can get them for a few cents each: www.ebay.co.uk/itm/273212998941 I think that you could probably run a whole string of them in series from a single stepper driver. They will do 20,000rpm and then explode on only 5V, so series wiring ought to not be a problem for slow speed stirring. I wouldn't be too concerned about immersing motors in liquid. Cars, bikes and aircraft all do it in the fuel tanks. I think water is the best choice, it's an easier clean-up when the cat knocks them off the tree and smashes them.
Does a snow globe (or in this case, a fog globe) work with this? Manually shaking it up and a long settling time? Basically, is it satisfying, or would a really small amount of fluid be needed?
That is an interesting idea. You could try making one, see @4:55 to @5:11 to get an idea of what a snow globe may look like. I would say there is a settling time of about 10 seconds until the fluid is "calm". If you were to experiment with different fluids/viscosities you may find a longer settling time. I also tested putting small ball bearings in the ornaments to further agitate the mixture (not shown in the video).
@@WillKnott I was also thinking mineral oil might work and reduce the corrosion on the motor. Question is whether the concentrate will mix properly with it.
Don't really do stuff like this so my comment may be... uninformed, but here goes: why couldn't you get a motor with a longer shaft so you could keep the motor outside of the fluid? I realize you'd have to have washers/grommets/whatever to keep the fluid from exiting along the shaft, but it should be possible, no? Slightly less ornament-like, but you could hide the motor as part of a decorative hook for hanging, I'd think. Certainly an interesting project to do with my kid. I'm also thinking driving it based upon audio input might be interesting - music beat-matching sort of thing, maybe.
Good ideas, I did consider mounting something externally but don't currently have the appropriate parts; may come back to this project in the future. I also wanted it to still appear to be a "normal" ornament on the outside. The audio idea is interesting! Maybe a xmas song to fit the theme
Brilliant idea..

you could use a tiny button cell battery or solar cell. when the other xmas light are on the solar cell can provide enough to run a small fan
Super cool! Great watch. I’d love to know what they’d look like with an LED inside as well illuminating from the inside out

@@WillDonaldson That totally makes sense! Thanks for letting me know before I blew a breaker and a few LEDs😅
Awesome project, could be used as a potion for some cosplay or Halloween decorations.
Incredible. Love it! Learned a lot about a lot of things in this video. Appreciate your creativity.

Great idea Will. I predict a fantastic future for you. BTW I'd watch a studio tour, thanks.
Wow this is so creative! :O

Great video mate! Hope you keep making more! Subbed!

I wonder how mica powder would behave suspended in distilled water.
maybe you could force movement of liquid with heating element, like in lava lamp
Thermal convection currents work well, although for the best result you'll also want a large heat sink

Glycerin is usually used in snow globes to slow the fall of flakes. Would that work with or against the fluid for settling?
