PICTURES OF JAPANESE 1-YEN COINS; "FLOATING"

HERE ARE SOME PICTURES OF JAPANESE 1-YEN COINS

I "LIBERATED" SOME TOOLS FROM DELTA AIRLINES


THIS IS THE "OBVERSE" OF A 1-YEN COIN


THIS IS THE REVERSE OF A 1-YEN COIN


PICK UP A COIN WITH A PLASTIC FORK, COURTESY OF DELTA AIRLINES



CAREFULLY PLACE 1 COIN ON THE SURFACE OF THE WATER





CAREFULLY PLACE SECOND COIN ON THE SURFACE OF THE WATER


CAREFULLY PLACE THIRD COIN ON THE SURFACE OF THE WATER


CAREFULLY PLACE FOURTH COIN ON THE SURFACE OF THE WATER; NOTICE THAT THE COINS HAVE DRIFTED TOGETHER



CAREFULLY PLACE FIFTH COIN ON THE SURFACE OF THE WATER


CAREFULLY PLACE SIXTH COIN ON THE SURFACE OF THE WATER; THE PREVIOUS FIVE HAVE DRIFTED TOGETHER AND NUMBER 6 FITS IN, LEAVING ONE SPACE.


CAREFULLY PLACE SEVENTH COIN ON THE SURFACE OF THE WATER; PLACE IT NEAR THE
EMPTY SPOT AND IT DRIFTS IN. NOTICE THAT THERE IS A LITTLE WATER ON TOP OF THE SEVENTH COIN, IT IS LIKELY THAT IF WE ADDED ONE MORE, THE SURFACE TENSION WOULD NOT SUPPORT IT AND THE WHOLE ASSEMBLY WOULD SINK.

SO, FOR NOW, THE WORLD'S RECORD IS SEVEN COINS. CAN YOU BEAT IT?

What a treat to see an investigation in progress while in flight! Impressive. I'll pass it on to Max.

my name is Ulysses Dolan, my teachers name is Kelley Dean(212). these coins are really cool. my math challenge co-teacher, Dr. Steve showed them to us, they are amazing!!!!!!!!!! there obviously less dense than the water other wise they wouldn't float.
