Will it Float?
The Tata
Nano is a fun car. It's got a great pick up, is nimble for city driving, and
chock full of tech features. And while it may not sell for Rs.1,00,000 any
longer, it can still fit 4 for a comfy ride and give 30 km/l. All of this
thanks to a rear-mounted engine, low centre of gravity and a spacious, light
frame…all of which is both good and bad, as I found.
The
serene IISc campus is self-contained. One just does not want to leave it for
the hustle and bustle (and the occasional wrestle) of the city. The couple of
jaunts I have had off-campus with the Nano have been to some spanking new malls
nearby. The Orion Mall and the Mantri Mall are a world of their own. A rich
blend of up market international brands standing shoulder to shoulder with
locally grown shopping chains. Subway and Shanti Sagar are cheek by jowl. Levis
and Crocs lie alongside Landmark and Bata. Fancy a massage to relax after some
heavy duty shopping? Coin operated massage chairs line the aisle! You might as
well be in any large mall in the US, but for the sea of desi faces. If you were
in the Bay Area or New Jersey, even that is moot. But then, there are still
those oddities and niggles that remind you that we're still growing into the
consumer-driven economy (Is that good? For a
different post). Like the water fountains whose spouts are 5 feet high
(maybe it's a shower?!!). Or the eternally empty towel dispensers. Or the
strategically placed buckets to catch water dripping from the roof during a
downpour! Jugaad is in full flow.
And yes,
it does rain a lot in Bangalore, as I've found. While the first couple of weeks
here welcomed me with sunshine, last week more than made up for it with several
showers. One might as well have been in Redmond. In fact, last weekend
supposedly recorded a 30 year high rainfall!
Not that I knew about it then when I sauntered out. But in all, it's been fun
watching the showers through the tree tops from my vantage office at the top
floor of SERC (whose roof wasn't immune to the torrent either :-)).
Maybe
there is something about water that spurs innovation, reflecting through
showers or musing in the bathtub . Archimedes would agree. Even Prof. C.N.R.
Rao, during his recent Bharath Ratna felicitation on campus, drew inspiration
from Archimedes discovering the science behind buoyancy and rushing out his
bathtub shouting 'Eureka'. Which reminds me of my PhD co-advisor, who often
used that expression when he regaled our lab group with anecdotes. I guess it
is nice to be able to explain something as fundamental as floating that we take for granted. But one
thing I never understood was Archimedes' rush to share his discovery in his
state of undress (as the story goes). It was not like he had to publish it soon
out of fear of being "scooped".
So what
does Archimedes share with David Letterman? For those not familiar, Letterman
is a late night comic, famous for this toothy grin. And, maybe picking the
wrong message from Archimedes' story, he runs an occasional segment called
"Will it Float?". It is one of his better bits where he'd try to dunk
commonplace stuff into a tank of water to see if they would float or not. He's
tried things as odd as a canaloupe (floats!) and 500ft roll of coaxial cable (floats!!). It was never an easy guess, so
maybe there is a science lesson there? But one thing I'm sure he's not tried
this on is a Tata Nano. And (drums please) ladies and gentlemen, today, we have
an answer!
Finding
the right entrance into IISc campus is a bit troublesome, what with road
construction that makes many gates inaccessible. I had finally figured out a
reliable route through Maramma Circle. But then, there are always boundary
conditions one finds out about. As I was driving back my Nano from Mantri Mall
last Sunday night, in poor visibility caused by the record breaking rains, the
comfort of being able to find the gate soon gave way to the boundary condition
of navigating the flooded underpass.
So how
many engineers does it take to estimate the depth of water in an underpass
(caveat: at night, and in a downpour)? The answer, apparently, is Not Enough! My cousin, a partner in crime, and
myself "pool" our collective aeronautics engineering and computer
science skills together and make a quick decision: Nah, it's not too deep. So I
rev up the engine and head down the slope at a measured pace…
Well, the
good news is, if you always admired those cool cars that Bond has that you can
drive on land and skim through water, Nano gets you close! But in the absence
of a hydro-propulsion mechanism , you are (literally), a sitting duck in water.
Long story short, we almost make it to the deep end, the wheels loose contact
with the road -- the car floats!! -- and
the low-slung rear engine splutters out. In hindsight, we should have tried to
get out thru the window but, oh well, 2ft of water pours in as we step out the
door. A few heaves and hos, and me manage to push the car uphill. Our escapade
at least proved a cautionary tale for several cars following us, which soon
turned tail and headed off to better pursuits.
After all
these amphibious adventures, the Nano had to suffer the ignominy of being
paraded through Bangalore streets on its hind wheels by a tow truck, as
passers-by gave it a sad look. The little car that almost could…
P.S. I
know an unnamed student of mine is rolling with laughter now, after the ribbing he
got after a similar incident, though with better results!
