Default Bring on the vibrators (yeast starters)

While watching Brewmasters a while ago, I noticed that their yeast girl (Does that sound weird in a thread about vibrators? Let's go with lab lady) was testing / propagating yeast in a flask similar to the ones many of us build starters in. But rather than using a stir plate, the vessel appeared to be on some kind of vibrating platform.

Is this common in commercial breweries? Does anyone use a similar method at home? It seems as though something like this would be easy and cheap to make with a handheld massager or adult toy and a little ingenuity. As long as the flask and wort are in constant motion, it would seem to be effective.

Thoughts? Has anyone tried this?

I think it's a swirl-er.

This thread has the same potential as the hot tub mash tun...

Lab shakers of various types are pretty common in most research labs.

Another motor to consider, though less fun are the ones used in video game controllers.

Yeah, an orbital shaker is what you want. A vibrator isn't going to work. Look for something like this: http://cgi.ebay.com/Bellco-Mini-Orbital-Variable-Speed-Lab-Shaker-774408096-/150552945824?pt=LH_DefaultDomain_0&hash=item230da7 a4a0#ht_4215wt_905

I hope you have money for a contraption like that. They're expensive. We have one at my school that's like a $13k machine. Granted that thing will hold like 10-5L flasks so I'm told.

Thanks for the link, Revvy. After reviewing that, I'm confident that stir plates are the way to go! Although I'd still like to find a way to use sex toys in brewing.

Off to the memorable quotes page we go...And maybe this will end up in someone's sigline as well.
