This was the final version of the teleporter created for trick-or-treat 2017. The illusion worked well; however, I didn't leave myself enough time to add more "bells and whistles" to the teleporter or to polish the mad scientist skit. As I say in the video, I'm not sure it was worth the time and expense for a two-hour trick-or-treat. In the end, I decided to use regular glass with reflective window film for the chamber rather than two-way mirrors. The two-ways would have done a better job, but two panels would have cost several hundred dollars. Just the regular quarter-inch glass cost nearly $200. You know what it's like: You get an idea and--sometimes against common sense--just have to know if it will work. It did but could have been better.
