Badow! (This is not my vid.)
So the lab down the hall was trying to make some extra space, and invited everyone over to swipe whatever glassware/equipment they wanted. Among the stuff was a pristine 1531. Works perfectly, self-calibrates, goes from 100 RPM to 25,000 RPM, and has inputs and outputs for syncing up to a camera for high-speed photography.
SCORE!
Oh holy moley that’s boss !!! You got it for FREE ???
What kinda lab did you say you worked in again ?
Yup. Free. They used to use it for a teaching unit in one of the biology labs, but they’d discontinued that lab years ago. I guess it had been sitting in a cabinet for 20 years, and its purpose had been forgotten. Of course, I saw it and went, “HOLY SHIT.”
Hey, take it to the county fair. It’s August. They’re everywhere !
" Are you an Epileptic??? Find out !!! "
( I know. It’s not P.C. My apologies to those who have Epilepsy who are Dopers, who know someone who has it, etc. But it IS a tempting way to make a few hunnerd dollars a night 
)
Congratulations, Cartooniverse. You and I are apparently the geekiest geeks in Geekville.
I am definitely going to try to work that out. In the meantime, however, I also got one of those electric rotators along with a ton of “optical illusion discs”. I’m going to work it into our band’s stage show. 
HA !!! on the Soundtrack link !! Freakin’ brilliant.
So…your band… The Geektones… Sponsored by The Straight Dope… touring North America in support of its new album, One Dope Over The Line featuring the viral single " Cite Ashun Nation ".
