Engineers build a massive Bat Signal that actually works
It's more complicated than you might think.
Even those who aren't fans of superhero movies are familiar with the Bat Signal. This distress signal device, which has appeared in the various interpretations of the Batman mythos, has become as iconic as the Batman himself.
From a technical standpoint, it's a specially adapted Klieg searchlight with the sign of a bat attached to it. The Gotham City Police Department uses it to project a bat emblem on the sky or buildings of Gotham City in order to contact and summon Batman to their aid in the event of a dangerous catastrophe.
In this video by the YouTube channel Hacksmith Industries, you can see just how difficult it is to recreate the Bat Signal in real life. The engineers managed to do it thanks to some high-level engineering and problem-solving. If you're curious to know more, make sure you watch the video embedded above, and as always, enjoy.
