The Krummlauf, which translates to "curved barrel" in German, was an innovative yet peculiar solution for specific combat scenarios. It was primarily intended for use in armoured vehicles and urban warfare. | Simple History

Esta arma existió de verdad. La Krummlauf tenía el cañón curvado para disparar desde esquinas o dentro de tanques sin mostrarse. Una idea brillante… pero mortal. El metal se rompía por la presión, y podía estallar en las manos del soldado. Un invento adelantado a su época, que terminó prohibido. ⚙️💥 #HistoriaOculta #ArmasExtrañas #SegundaGuerraMundial #Curiosidades #Militar #MisteriosHistoricos | El Abismo

But in the water and oil mix, only part of the rod vanishes, creating an amazing visual effect. It's an engaging and simple way to understand optical physics in action! #TheDadLab #OpticalIllusions #homeschooling #ScienceExperiments #scienceisfun | TheDadLab | Facebook
