The shooter nearly runs him over as he does a U-turn and drives away.

"At that point, the car behind us does a U-turn, pulls out into the other lane, does a U-turn, comes back and aligns himself right next to my driver's side," said Feldman, who explained that his security didn't see because he was focusing on the other man.

Even though our talk has turned emotional, she laughs easily and listens thoughtfully, as the car does a U-turn towards the venue.

The first option would make it harder for Sanchez to become prime minister, unless he does a U-turn and allows Iglesias and other senior Podemos figures to have key cabinet positions.

If Johnson does a U-turn and goes "soft Brexit," then keeping the UK close to Europe really helps Johnson with the Northern Ireland issue, by keeping NI closer to the EU. It saves him lots of hassle.

"Frankly, the concern is that if the Trump administration does a u-turn on climate change in terms of its commitment to Paris Agreement and its commitment to move in lockstep with the 173 countries in addressing this challenge, it would have a negative effect on ability too right climate change but would affect its abilities to advance other interests in the world," Bodnar said.

After sliding down, the logs pass two realistic sculptures of African elephants that squirt water just above riders' heads. While turning again, the logs pass a Polynesian village, small gardens, and fountains. Eventually, the logs go up largest, most notable hill, does a U-turn and takes its plunge, does yet another U-turn, and returns to the boarding dock.

Nozzles direct forceful, high-speed streams of water against a series of spoon-shaped buckets, also known as impulse blades, which are mounted around the outer rim of a drive wheel (also called a runner). As the water jet hits the blades, the direction of water velocity is changed to follow the contours of the blades. The impulse energy of the water jet exerts torque on the bucket-and-wheel system, spinning the wheel; the water jet does a "u-turn" and exits at the outer sides of the bucket, decelerated to a low velocity. In the process, the water jet's momentum is transferred to the wheel and hence to a turbine.

The water's velocity, roughly twice the velocity of the bucket periphery, does a U-turn in the bucket and drops out of the runner at low velocity. In 1879, Lester Pelton, experimenting with a Knight Wheel, developed a Pelton wheel (double bucket design), which exhausted the water to the side, eliminating some energy loss of the Knight wheel which exhausted some water back against the center of the wheel. In about 1895, William Doble improved on Pelton's half-cylindrical bucket form with an elliptical bucket that included a cut in it to allow the jet a cleaner bucket entry. This is the modern form of the Pelton turbine which today achieves up to 92% efficiency.
