When Sarah is first at the table talking to Chris, the spirit box is on the table in front of them while they are both in frame. Then the camera switches to Sarah. Switches back to both of them and Chris reaches over to the left of the screen to get the spirit box as it has vanished from the table in front of them.
About 10-15 minutes in, "Chris" uses a ghost meter to check the electromagnetic anomalies around the box. He shows himself moving the meter closer and farther away multiple times and when it gets close it beeps very quickly. Then at one point after moving it up and down under the box, he brings the meter back to the top to move it up and down above the box, but when he moved it past the box on the side, even though it was closer for a few seconds, it didn't beep or light up at all.
When the ceiling fan gets mysteriously 'ripped from the ceiling', there are no wires of any kind protruding from either the ceiling mount or the falling fan component. Non-prop / actual ceiling fans have wires.
