Using elementary knowledge of Special Relativity, we design a computationalclassroom experiment in excel and python. Here, we show that any inertialobserver $\mathcal{B}$ with an arbitrary speed $u_\mathcal{B}$ is associatedwith a unique event ${E}$ along the worldline of Rindler observer$\mathcal{R}$. The inertial observer $\mathcal{B}$ records the velocity of$\mathcal{R}$ to be non-zero at every instant except at this unique ${E}$ whereit is co-moving with $\mathcal{R}$. At this event, $\mathcal{B}$ records aminimized distance to $\mathcal{R}$ and a maximized acceleration of$\mathcal{R}$ along its worldline. Students grasp the concept of properacceleration when they realise that though an inertial observer measuresvariable local acceleration but this maxima is the same for all inertialobservers. Since the Rindler observer is associated with variable localvelocity the time dilation factors are different. Parameterising the Rindlervelocity by proper time we graphically present the concept of time dilation. Weassume $\mathcal{B}$ to be moving with respect to an inertial observer$\mathcal{A}$ which is at rest and their clocks synchronize to zero when theymeet.
