Happy Halloween!!! Your friends at Unprofessional Engineering have whipped up a real treat for you this year by looking at the manufacturing process for some of your favorite Halloween treats.

We've looked at how Hershey's Reeses Cups are made, both the left and right side of a Twix, as well as the general process for gummy candy. In addition, Luke and James fight to the end about which candy is the best to end up in your bag of treats, as well as which ones are more of a trick.
