When the duo are in the hi-tech bedroom, and Ollie rides the bed back out of the wall, the following sequences show that the rotating table is first clear, then has the pipe and magnifying glass back on it, then is clear again, and then has the chairs re-arranged.
When Laurel goes to turn off the light and accidentally sends Hardy's bed into its hiding space in the wall, Laurel's pipe and magnifying glass are on the table. Laurel panics and begins pushing buttons. When he hits the button that spins the table into the floor, you can see the pipe and magnifying glass go flying. When the table returns, you can see they are still not on the table. But when Hardy's bed comes back out of the wall and Hardy falls from the bed, as the camera follows him, the table can be seen and the pipe and magnifying glass are sitting there.
