 The ride usually culminates with a rapid descent and splashdown into a body of water, which may happen more than once (normally the largest drop being just before the end).It provides people with an entertaining way to get wet and cool off on a hot summer day, with certain seating sections usually being splashed with more water for a more fun and wet ride.Log flumes are a variant of the chute rides and old mill rides that were popular in the United States in the early 20th century.
