Explanation: For this round, MythBusters Adam Savage and Jamie Hyneman went viral to verify whether a popular poolside YouTube clip floats in the real world. The footage shows a man sliding down a waterslide and landing a seemingly impossible distance away in a kiddie pool. By MythBusters' calculations, the YouTube superstar got around 115 feet (35 meters) of hang time, sailing through the air at a speed between 40 and 45 miles per hour (64 and 72 kilometers per hour).
In true MythBusters form, Adam and Jamie constructed a supersized waterslide to match the one featured on the video. But to ensure that they would swim rather than splat upon landing, they constructed the monster slide in front of a lake instead of a tiny pool. The final product stood 12 feet (3.7 meters) high and around 165 feet (50 meters) long with a 30-degree slope.
The lake target ended up being a saving grace, since both Jamie and Adam fell far short of the myth's 115-foot (35-meter) mark. Each dropped around 70 feet (21 meters) from the slippery slide, busting the myth's dazzling distance factor.
After repeated runs, the MythBusters noted that the precise accuracy involved with the YouTube myth is plausible — as long as you're aiming for a bull's eye much closer than the Internet video would have viewers believe.
