The scientists "...have succeeded in levitating small mice using a 17-tesla magnet. The magnetic field is so strong that it affects the water in the animal's tissues, prompting a repulsive magnetic forse that suspends the rodent in the air. It takes a superconducting magnet operating at minus 456 F to float a 10-gram mouse within a 2.6-inch bore, which is kept at room temperature."
"The magnetic field is applied evenly to keep the mice hovering in place..."
(and here's the part that sends me into totally unreasonable giggle-fits every time I read it),
"...and scientists say rodents acclimate to the test in about 4 hours."
Yeah, but for those four hours...
I mean, for their little brains to be overwhelmed with little mousey, "WTF!WTF!WTF!" thoughts for four solid hours?
And then, how do you know that they're "acclimated"? Do they just suddenly realize, "OK, I'm floating. It's cool".
And is someone observing them to see when the "Oh, $#*t!" look leaves their little beady black eyes?
I'm sorry, but every time I read into the implications of that single dry statement, the old ethologist in me gets the giggles. Poor little mouseys.
