Corrected entry: When Burt and his wife are shooting the Graboids in their basement, he tosses her a magazine; he is kneeling and we see it tossed slightly up and then starts falling in the air, no more than 4 feet above the floor. But the camera angle changes and she catches it falling from her head height - she is 5'6" - so it magically rose about 18". (01:00:00)

Correction: Michael Gross is 6'3" and kneeling he would still be at least 4'8". When he throws the magazine it raises up and over the height of his head. When the magazine comes into view, it's only shoulder/chin height of Reba McEntire, which would be about 4'10" off the ground.
