On August 25, Emmett encountered his friend once again and demonstrated his rocket car to him.However, Emmett quickly lost control of the car, which ended up stranding Einstein on the roof of the Courthouse and then crashed into a bill board on another building.First, they managed to acquire alcohol by switching it with the soup at the Sisters of Mercy Soup Kitchen (which was run by Irving "Kid" Tannen) and having Edna Strickland deliver it to Emmett's house by allowing her to host the next meeting of the Stay Sober Society there.Then they managed to steal Arthur Mc Fly's hat from Kid Tannen and had Einstein sniff it and managed to track down Arthur Mc Fly and handed him the subpoena.Emmett returned home to pursue the life of science he was supposed to have, but this time without his fear of fishing.In his youth, Emmett played sandlot football, gaining the nickname "The Streak" due to his quick reflexes.Around this time, anti-German sentiment had increased in the United States due to Germany's involvement in World War I, so Erhardt had their family name changed from Von Braun to Brown.
Emmett's stunt was recorded, and he was heralded as "Daredevil Brown". Tannen proposed a very dangerous stunt, going over Niagara Falls in a barrel, but promised that a dummy would take Emmett's place.
Shortly afterwards, Edna Strickland (who had come to dislike Emmett following the incident with Stay Sober Society) came to him and referred to his rocket car as a public hazzard and mocked the very idea of flying vehicles.
During their argument, Emmett's future self saved Einstein from the roof, which left Emmett wondering how Einstein managed to come down.
Deciding to distract his father, Emmett started an argument with him regarding Emmett's future career, providing his friend clues on how to complete the rocket drill by emphasising certain words during the argument.
After the rocket drill was completed, Emmett quickly ended the argument with his father and asked the young man when he could expect a response from the patent office.
