AntiGravity

You negate the mass of a creature of size large or smaller and all of its equipment, or a non magical object no heavier than 400 pounds, that you can see within 60 feet. The target has no weight, no mass and isn't influenced by any gravitational attraction. The target can be carried without any effect on carrying capacity, and as an action, can be shoved and will immediately move 40ft., and continue to move at the top of each subsequent round, moving 10 ft. less each round. It moves in a straight line unless shoved again or stopped, the spell ends or it comes to rest. If the target is a creature, it can use its movement to push itself off a surface within reach to the same effect as being shoved. Otherwise, its movement speed is zero. If the object is shoved again, the movement from the previous shove stops and it moves under the effect of the new shove.

If the target is within a vacuum, it will move at 40ft. each round until the spell ends or an external force acts to stop it. If the target is under water, it will move initially 20ft. then 10ft. less each round.
