'Drunk' revellers turned BMW into swimming pool to cruise the streets in Germany 
  
  
  
 German police were left speechless at the weekend when they stopped a group of inventive revellers cruising around town in a unique swimming pool-car. 
  
  
  
 The water wagon was spotted careering along Eibenstock near Chemnitz, southern Saxony, by a lone police sergeant on motorcycle. 
  
  
  
 'I saw the strangest-looking convertible I have ever seen - a roofless BMW, without registration plates, bordered around the open top with wooden boards and fake plastic flowers. It was also full of water,' he later said. 
  
 Bizarre: Police in Germany pulled the vehicle over to discover it had been turned into a makeshift swimming pool 
  
 Aside from the driver, the car held three young males clad only in swimming trunks - one of whom was lolling on the boot with his feet dangling down into the vehicle. 
  
  
  
 'All of them appeared drunk,' the police said. 
  
 The sergeant ended up chasing the BMW as it sped off into a car park - losing much of its liquid load as it went. 
  
 The young men sloshed to a halt and jumped out, fleeing across a nearby dry riverbed, where they hid as police swarmed around the vehicle. 
  
 'Strange': All three of the swimming trunks-clad passengers travelling in the vehicle 'appeared drunk', police said 
  
 It turned out the DIY car crew had hollowed out the inside of the vehicle, sealed and waterproofed it, painted it swimming pool blue and filled it with water for a grand day out. 
  
  
  
 Concerned that the men would try to return and make a getaway, the sergeant let the air out of the tyres and disconnected the spark plug leads. 
  
  ||||| A BMW convertible first aroused the suspicions of a motorcycle cop on patrol in the eastern German town of Eibenstock when water sloshed out of it as it drove around a curve. When the officer pulled the car over, he could hardly believe his eyes. 
  
 In a police report released on Monday, he described encountering an "a convertible of a slightly different kind." The car had been converted into a swimming pool on wheels complete with a wooden railing and cheap floral decoration that could have come out of a chintzy Hawaiian hotel. 
  
 In addition to the driver, the officer also found two young men sitting inside in bathing suits and a third sitting on the trunk, dipping his feet in the "pool". The car reportedly only had one functioning gear, but could travel at speeds of up to 25 kilometers per hour (15.5 mph). The vehicle was also lacking a license plate. 
  
 DPA/Polizei Chemnitz Police became suspicious when water began sloshing out as the car rounded a corner. 
  
 With the cop in hot pursuit, the men drove into a parking lot, jumped out of the car and fled the scene -- likely, the officer believed, because they were drunk. Police found that the car had been sealed using synthetic material and filled with around 2,000 liters (530 gallons) of water. It attracted so many spectators that the officer had to call for reinforcements. 
  
 But Is It Illegal? 
  
 A 27-year-old recognized by the police officer as the driver later returned to collect his belongings, but claimed he hadn't been behind the wheel. Police had let the air out of the tires and disconnected the spark plug by then to ensure it couldn't be driven further. The police said they let the man take his shoes and wallet but ordered a blood test to determine whether he had been drinking. 
  
 Since then, the men have had second thoughts about the caper. One of them told the tabloid Bild that "the ride was a stupid idea. It was the first time we drove on a street and we just wanted to have a little fun." 
  
 Police are currently investigating possible charges for drunk driving and driving without insurance. But there's one question that even police experts have been unable to answer: Is it illegal to drive a swimming pool? |||||
Output:
The "carpool" has finally gone literal: Four men decided to beat the heat in Eibenstock, Germany, on Sunday by taking a ride in a convertible—only this was "a convertible of a slightly different kind," according to police. Carved out, sealed, and filled with some 530 gallons of water, it had been transformed into a swimming pool on wheels, complete with blue bottom, der Spiegel reports. It drew police attention when an officer saw water splash out—and with its single working gear and top speed of 15.5mph, the bathers didn't get far. What the officer found, per the Daily Mail: A "roofless BMW, without registration plates, bordered around the open top with wooden boards and fake plastic flowers." He also spotted a driver inside, plus two men in bathing suits and a third sitting on the trunk, dipping his toes in. All took off, but when the 27-year-old who was believed to be the driver returned to get his things, police got a blood sample; if he was drunk, he could face charges. One of the men told Bild, "the ride was a stupid idea. It was the first time we drove on a street and we just wanted to have a little fun." Funny footnote: Police aren't actually sure if driving a swimming pool is illegal.
