Pastor Maldonado emerged fastest from the second Friday practice session for the German Grand Prix at Hockenheim, as rain showers meant the order was largely decided by who was on track at the right moment.
Heavy rain before the session meant a distinct lack of Formula 1 cars on track at first, bar Bruno Senna doing an installation lap in the Williams that Valtteri Bottas had crashed in the morning.
It was 20 minutes in before Jean-Eric Vergne, Charles Pic and Nico Rosberg came out and got the afternoon underway in earnest. Conditions were steadily improving at this stage, and a quarter of an hour later Rosberg switched from full wets to intermediates on his Mercedes, a move everyone else soon followed.
With the track getting quicker by the moment, the top spot then changed hands constantly after the next 25 minutes before the rain returned, ending the run of relatively quick times. Maldonado put his Williams on top with a 1m27.476s just before then, and that stood as the fastest of the session.
Most drivers came back out after the second shower passed, but found the track too wet to improve their times. There was still time for some incident though, as Michael Schumacher crashed the other Mercedes on the way into the stadium section, prompting a red flag with four minutes left that effectively ended the session.
Toro Rosso's Daniel Ricciardo also hit trouble late on, sliding into the gravel at the Sachs Kurve and getting beached.
Rosberg ended up classified second, ahead of Sebastian Vettel's Red Bull, Sergio Perez's Sauber and Romain Grosjean's Lotus.
Everyone managed a reasonable amount of running despite the conditions, with the exception of Pedro de la Rosa, who spent a long time in the garage while HRT worked on his car's brakes, meaning he missed the best of the weather.
