How to Make a BATSIGNAL (For Real!)

In this video I build a bat signal from a lensed flashlight beam. This design can be used to project any image, or simply act as a spotlight. For the light source I'm using the Imalent MS18 flashlight, which you can check out here (this is not a paid endorsement, but I was sent the flashlight for free to use in this project): https://www.imalentstore.com/products/imalent-ms18-100000-lumen-flashlight Similar fresnel lenses as the one I used in this video are available on eBay. I used a lens 250mm in diameter with a 500mm focal length. You can find some here (this is an affiliate link): https://ebay.to/2In1Nzt Thank you very much to all of my Patreon supporters who have contributed to help me create videos like this one.

Why does the clear plastic is not melted or burnt?

The clear plastic doesn't absorb very much light so it doesn't get hot, but the bat emblem might melt if I left the flashlight on too long.

Ha, this is awesome! Good for one-off art projections as well. And if you combine this with fluid slides (like they used in the seventies) you can even use the heat to your advantage, while producing some trippy images.
