[Update: Splash Mountain was replaced by Tiana's Bayou Adventure in 2024] While the original Splash Mountain is gone, its successor, Tiana's Bayou Adventure, uses the exact same flume and drop structure, and yes, you definitely feel the "stomach drop" on the final plunge. The drop is a 52-foot (16-meter) descent at a 45-degree angle, reaching speeds of roughly 40 mph. The "stomach drop" sensation, known scientifically as negative G-force, occurs because your body and the log flume are accelerating downward faster than your internal organs. For a split second, your organs are essentially "floating" inside your body, creating that tickling, weightless feeling in your midsection. This sensation is most intense if you sit in the back of the log, as the front of the vehicle is already partially down the slope by the time the back reaches the peak, causing the rear to be "pulled" over the edge with more momentum. While the ride is mostly a slow-moving "dark ride" featuring animatronic music and storytelling, the final drop is a genuine thrill that provides enough "airtime" to make your heart jump before the big splash at the bottom.
