This rare footage from Barcelona in 1913 shows one of the most unusual vehicles ever built — a lightweight car powered by a rear propeller. Designed as an experimental mix between early aviation and automobile engineering, this tiny machine was so light that two men could lift it off the ground. In this restored and colorized clip, you can see the propeller spinning as the car drives through the streets, surprising bystanders and showcasing the creativity of early 20th-century inventors. #colori
