So, this isn’t at all about lighting, or solid-state, or technology. It’s just a gadget cat toy we call the Cat-apult.

Shown in the “cocked” position, the lever arm is sprung by rubber band. This is released by the trigger when depressing the pedal at the rear. The launch tube guides the snack projectile and keeps the cat from stealing the treat inside, while also protecting him/her from the lever when it is released.
