Homemade Batsignal Reaches the Clouds (and how to make an image projector for yourself!)

In this video I test my DIY bat signal powered by the incredibly bright Imalent MS18 flashlight against the clouds. I also show an easy way that you can build your own image projector using a few common items. This is a great project to learn the basics of how lenses work, and can be used to build your own mini bat signal! Thanks for watching! -Ben
