Olympic Torch: ATHLETES ARE NOT THE ONLY ONES WHO HAVE PUT IN LONG HOURS PREPARING FOR THE OLYMPICS. A TEAM OF ENGINEERS AT GEORGIA TECH HAS SPENT THE LAST YEAR GETTING READY FOR AN EVENT THAT'S AS IMPORTANT AS THE SPORTS--THE OLYMPIC TORCH RELAY. CARRYING A BIT OF FLAME TRANSPORTED FROM GREECE, THE TORCH HAS BEEN RACED AROUND THE COUNTRY FOR THE LAST FEW MONTHS--SAM SHELTON WAS IN CHARGE OF BUILDING THE TORCH. Shelton: "it was an interesting merger of both the arts and technology" SHELTON AND HIS TEAM WERE GIVEN AN ARTISTIC DESIGN THAT THEY HAD TO TURN INTO A VERY FUSSY KIND OF TORCH. Shelton: "number one it had to be light in weight, you didn't want to encumber the runner any more than you had to. . . some of the other chraracteristics, were of course that it needed to be an art object, it had the look that the olympic committee had created, the flame itself needed to be robust in such a manner so that the wind does not extinguish it, the rain does not extinguish it." THE FINAL TORCH IS A MERE 3 AND A HALF POUNDS, BURNS FOR 45 MINUTES, AND MOST IMPRESSIVELY, STANDS UP WELL TO WATER. SHELTON AND HIS TEAM TRIED MANY FUELS BEFORE SETTLING ON PROPYLENE THAT WILL KEEP BURNING DESPITE RAIN DROPS. Shelton: "What actually happens is the fuel and the air actually will bubble up through the water and the flame will stay ignited on top of the water." THE TORCH WILL ARRIVE IN ATLANTA ON JULY 19TH AFTER BEING CARRIED THROUGH MORE THAN 3,000 CITIES. THAT HARD DEADLINE FOR BUILDING THE TORCH WAS ONE OF THE TOUGHEST PARTS OF THE JOB SAYS SHELTON. WAS HE EVER WORRIED THEY WOULDN'T MAKE IT ON TIME? Shelton: "oh absolutely, but thanks to the Olympic spirit by many many manufactureres and many parts suppliers we made all the deadlines.. . and it really has been an Olympian effort."
