I have been trying to think of a way to add a smoke effect to my Matty Trap without having to do much modifications. What I settled on doing is using the empty space inside the trap it's self. I plan on making a mini smoke machine using the typical ecig with micro aquarium air pump and just attach it to the inside of the trap. Then I am going to cut another piece of frosted acrylic and place it on top of my fog machine and keep it held in with magnets. What I need to know is the dimensions of the inside so I know what size to cut the acrylic. Does anybody have those dimensions?
