I've made 2 magnetic stirrers for myself now. They're easy to make and work pretty well (though it does take a fair bit of time to put together). You can set your juice to mixing and just walk away to measure out a new batch. If you're handy and like to tinker, its a really fun project. I learned quite a bit about working with electricity and wiring from this project.

I think all told, each mixer costs me roughly 15$ to make, and probably about 3-4 hours of labor and tinkering.

All you really need is:

• a computer fan
• a power supply
• a dc motor controller, with potentiometer (potentiometer is just a dial that lets you adjust spin speed)
• 2-4 small magnets
• magnetic sir bar (buy a variety pack: size of the stir bar makes a big difference: too small won't stir well, too big won't spin at all. You'll want a few different sizes at least)
• a box
• scrap wood, couple nails / screws, glue or other adhesive

Edit: you'll probably also want some kind of beaker or flask large enough for the whole batch, so you can mix before you bottle. You can find these at many vape suppliers, nic river and nude nictone both have some available.

Fan: Pretty much any generic tower fan works, but very small fans might have trouble turning the magnet bar smoothly.

Power Supply: You need a power supply that provides the same # of Volts your fan requires, and at least as many amps as the fan needs. If my fan says 12v / .5amps, I'll need a supply that provides exactly 12v and at least .5 amps. (Most tower fans I've seen run 12v and .1-.5 amps. A 12v / 1amp power supply will probably work with almost any pc fan.)

Controller This is the dc motor controller that I've used in both my mixers. They work well and they're not super expensive (~$8.50)

Magnets You can use pretty much any magnets. Simply glue your magnets onto the middle of the fan (make sure you have one positive side and one negative side facing up, so the stir bar holds at both ends.) For my first mixer, I removed a magnet from a hard drive, and supplemented it with a magnet bar I had from an old name tag. For the second mixer, I just bought some circular neodymium magnets from home depot; they were only a few $ and saved me a lot of time breaking open the HDD.

Box I used a small plastic box from home depot's storage solutions section. Cost about 3$.

Ps: Or there's always my old solution: put 2-3 bottles in a sock, and swing it around like a sling. 45 seconds of that is usually more than enough.

The best alternative is time. Nothing beats it for flavor in my opinion. Try to mix ahead and stagger steeps.

If you own a Sawzall, go with that. If you have a orbital sander, you can approximate a vortexor. (Hold bottle on angle, press bottom edge against upside-down sander, near the center. It should generate a miniature whirlpool inside the bottle which will mix it quickly.

Nothing speeds up steeping, tho.

The last thing I would do with a fresh mix is stick it in the microwave. Unless by microwave you mean cool dark cupboard.

I wouldn't microwave your juice tbh. Give your bottles a quick whisk with this or something like it and let time do its thing. https://www.amazon.co.uk/Norpro-Cordless-Mini-Mixer-White/dp/B000E39LYO/

I recently started to mix small 30ml batches by throwing a few strands of high guage kanthal into a drill and dipping those downward into the unicorn bottle and going at it at a low speed. My drill can go super slow so it's been working nicely tbh.

Then, it's into a cool dark cabinet without fiddling for a month. Best way to steep baby!

That Sawzall trick is very interesting too. So do you just tape the bottle to the saw part?

If the noise isn't an issue the jigsaw/sawsall is the best option.

Those cheap nail/paint shakers aren't strong enough to thoroughly mix eliquid. A magnetic stirrer is good, but then you're adding more time and steps and cleaning to your mixing process. With the jigsaw you're mixing in the final bottle, not an intermediary bottle.

Ultrasonic requires a long time to mix, if it even completely mixes the solution. It also kind of forcefully causes lighter notes to escape the solution - because the bottle/liquid/air locations are static all of the volatiles are sent from the liquid to the air and are never reincorporated.

If none of those are an option, the easiest is to actually make larger batches in larger bottles, although you do end up using another bottle. So instead of 60ml in a 60ml bottle, do 220 in a 240 bottle. Since there's more dead space it's easier to shake than the smaller bottle, and you only have to shake for 15-20 seconds. I have a bum shoulder, so I have to use my non-dominant arm to shake, and it's easy enough doing it this way.

As others have said, there is no way to speed up steeping time. There was someone that did a test of speed-steeping with an ultrasonic, and it did kind of work. But if you didn't vape it right away it actually ended up being worse a few days after being put through the ultrasonic. And the light/fruit notes faded very quickly.

Nitecore makes a magnetic stirer but it's not cheap.

All of my mix goes into a mason jar and then I use a hand mixer for a few minutes. If you make larger batches I recommend highly.

Never ever microwave your juice. Also, there's no way to speed up steeping without ruining your juice.

Shake the bottle using your hands and leave the bottles alone to steep.

I have an IZEN Proshaker that works extremely well for 10-30ml bottles. It's a quality piece and not cheap, but I wouldn't be without it because it makes shaking flavoring bottles quick and effortless.
