1. 0:00He bent the roller [music] coaster's
2. 0:01loop out of shape. You see, it's the
3. 0:03first ride ever to go upside down, and
4. 0:05it cost him everything. So, of course,
5. 0:07his rival copies it bolt for bolt.
6. 0:09[music] But, the night before opening,
7. 0:11his test dummy comes back crushed like a
8. 0:13soda can. But, he can't miss the
9. 0:14opening. So, he grabs a hammer and beats
10. 0:16the bottom into a long, lazy curve. Does
11. 0:19he know what he's doing? Not really. His
12. 0:21rival laughs, then sneaks in and cranks
13. 0:23the sides together until the loop is
14. 0:25tall and skinny, so the first cart will
15. 0:27snap like a twig. The next morning, the
16. 0:29town lines up at the rival's perfect
17. 0:31circle, and the rival climbs in front to
18. 0:33show off. The owner climbs into his, and
19. 0:35as his cart tips over the first hill, he
20. 0:37finally sees the tall, skinny loop
21. 0:39ahead. But, it's too late. You see,
22. 0:41[music] a car can creep around a hairpin
23. 0:42turn at five, but take it at 60 and it
24. 0:45flips. A cart is fastest at the bottom
25. 0:47of a loop, and a perfect circle puts a
26. 0:49hairpin right there, which is what
27. 0:51crushed the dummy. But, his hammer made
28. 0:52the bottom gentle, and the rival's
29. 0:54squeeze moved the hairpin up top, where
30. 0:56the cart is crawling. So, he floats over
31. 0:58without a scratch. Just as the rival's
32. 1:00cart hits the bottom of that perfect
33. 1:02circle.
