1
00:00:01,503 --> 00:00:06,272
    START TO FINISH, IT TAKES   
  THIS MACHINE JUST 90 SECONDS  

2
00:00:06,274 --> 00:00:08,207
       TO STRING 60 BULBS       

3
00:00:08,209 --> 00:00:10,610
    TO MAKE A 30-FOOT STRAND.   

4
00:00:13,381 --> 00:00:15,615
      THE FINISHED STRANDS      
    ARE COLLECTED BY WORKERS,   

5
00:00:15,617 --> 00:00:19,318
  AND EACH STRAND IS CONNECTED  
  TO A DOUBLE-WIRED POWER CABLE 

6
00:00:19,320 --> 00:00:22,088
 THAT PREVENTS THE WHOLE STRAND 
         FROM GOING DARK        

7
00:00:22,090 --> 00:00:23,689
     IF ONE BULB BURNS OUT.     

8
00:00:23,691 --> 00:00:26,893
 THE DOUBLE WIRE IS USED TO MAKE
  REDUNDANT ELECTRICAL PATHWAYS 

9
00:00:26,895 --> 00:00:30,730
 BETWEEN THE BULBS AND THE POWER
 CABLE CALLED PARALLEL CIRCUITS.

10
00:00:30,732 --> 00:00:34,033
      THAT WAY ELECTRICITY      
     CAN BYPASS THE BAD BULB    

11
00:00:34,035 --> 00:00:38,104
  AND FIND ITS WAY TO THE OTHER 
   BULBS TO KEEP THEM GLOWING.  

12
00:00:38,106 --> 00:00:39,639
 ONCE THE CONNECTIONS ARE MADE, 

13
00:00:39,641 --> 00:00:42,341
  THE POWER CORD AND THE LIGHTS 
      ARE TWISTED TOGETHER      

14
00:00:42,343 --> 00:00:45,511
      INTO ONE TIDY STRAND.     

15
00:00:45,513 --> 00:00:49,215
EACH STRAND IS TESTED TO BE SURE
     ALL THE BULBS LIGHT UP.    

16
00:00:49,217 --> 00:00:51,717
        THEN THESE L.E.D.       
        CHRISTMAS LIGHTS        

17
00:00:51,719 --> 00:00:54,821
    ARE READY TO KEEP BURNING   
        FOR 25,000 HOURS,       

18
00:00:54,823 --> 00:00:59,125
      OR ALL DAY EVERY DAY      
     FOR THREE WHOLE YEARS.     

19
00:01:04,532 --> 00:01:07,066
      Narrator: WHAT MAKES      
     THIS LITTLE METAL CLIP     

20
00:01:07,068 --> 00:01:09,469
  STRONG ENOUGH TO SAVE A LIFE? 

21
00:01:09,471 --> 00:01:12,338
        WHY DOES IT TAKE        
    AN ACTUAL RACECAR DRIVER    

22
00:01:12,340 --> 00:01:13,538
     TO MAKE A RACECAR SEAT?
