About the project

Story

Way back in 2012, the Popinator had it's moment of fame, displaying a machine that would shoot popcorn directly into your mouth on voice command. However, upon further research, you will find that there is little to no technical documentation describing how it works in detail. Regardless of whether this machine is real, or just a PR stunt, I recently revisited this video, and was inspired by what I saw. So I decided to make my own similar machine. Only in my case, it launches M&M chocolates!

With my M&M launcher, all you have to do is say the word, and chocolate will be launched into your hands/mouth/cup!
