DOLLAR BILL BOOT CAMP:
     IT'S ONLY FOR THE FEW, THE PROUD. IT TAKES A WORTHLESS PIECE OF PAPER
AND MAKE IT INTO SOMETHING WORTH HAVING. IT'S DOLLAR BILL BOOT CAMP AND IT'S
NOT FOR THE FAINT OF HEART. 
     Church: "One of our tests is the dreaded crumple test. . . we take . . . the note , roll itup into a
cylinder, smash it down into a tube, pick it up roll it up in the opposite direction, smash it down into the
tube again and, and we do that 16 times.  The note has to still be recognizable."
     SARA CHURCH IS A PHYSICAL CHEMIST AT THE BUREAU OF ENGRAVING AND
PRINTING WHO'S BEEN WORKING ON THE REVAMPED VERSION OF THE 100 BILL.  HER
JOB AT BOOT CAMP IS TO GIVE THE BILL SOME STREET SMARTS AND MAKE IT HARD TO
COUNTERFEIT.  THE LATEST THREAT TO THE BILLS? COLOR COPIERS THAT CAN SPIT
OUT ALMOST PERFECT REPLICAS.  SHE AND OTHERS IN THE BUREAU'S OFFICE OF
COUNTERFEIT DETERRENCE HAVE COME UP WITH WAYS TO THWART THIS BY PLAYING
TRICKS WITH LIGHT.  
     CHURCH: "The kinds of things you can use to prevent color copying are . . . things that look one
way in one type of light and one way in another."
     FOR EXAMPLE  THE NEW 100 DOLLAR BILL SPORTS A WATERMARK.  YOU CAN
SEE IT IF YOU HOLD THE BILL UP TO  THE LIGHT, BUT A XEROX MACHINE CAN'T COPY IT. 
ANOTHER NEW FEATURE: COLOR SHIFTING INK THAT LOOKS GREEN WHEN SEEN
STRAIGHT ON AND BLACK WHEN SEEN FROM THE SIDE.  ONLY A SMALL PORTION OF
THE BILL WILL USE THIS EXPENSIVE INK, BUT THAT'S ENOUGH--BECAUSE THE INK IN A
COLOR COPIER CAN'T PERFORM THIS TRICK.  
     ALL THESE FEATURES HAD TO MAKE IT THROUGH BOOT CAMP BEFORE THEY
COULD WEAR THE DOLLAR BILL UNIFORM.  THEY'VE SURVIVED THE CRUMPLE TEST,
NOT TO MENTION SEVERAL CYCLES THROUGH THE LAUNDRY, A CEMENT MIXER AND
THE INTENSE PRESSURES OF THE PRINTING PRESS.
