To be neutrally boyant in water, the object needs to have the same overall density as the water, 1 g/cc. This means that the objects material will have to be a similar density to water, or it would have to be made up of different materials which may be dense or less dense, but have an total overall density that's equivilant to water. Some spoons and plastic utensils could be very close, but you could always consider a full can of beer or plastic bottle of juice - where the fluid inside has a similar density to water, while the air trapped inside may just counteract the higher density material that the vessel is made from.
what object will not sink or float but will stay suspended in the middle of water
No, it sinks
If the weight of the object is higher than the buoyant force the object SINKS. And the opposite happens if the weight is lower than the buoyant force. If it is equal, the object neither sink nor float, it is neutrally buoyant.
buoyant force is the result of the displacement of the fluid an object is in. if a fluid is displaced by the volume of an object, the weight of the fluid being displaced is pushing up on that object
Since the object is submerged, we know that the buoyant force is not sufficient to overcome the weight of the object, otherwise it would be floating rather than being submerged. Therefore, the buoyant force is equal to the weight of the displaced water, not the weight of the object itself.
neutrally buoyant
A synonym for an object with neutral buoyancy is "neutrally buoyant."

You can make a plastic bottle neutrally buoyant by adding just enough weight (like sand or rocks) to offset its natural buoyancy. This can be done by experimenting with different amounts of weight until the bottle neither sinks nor floats when placed in water.
Something that neither floats nor sinks, stay in the middle of the tank or water subject it's in. Exp: bamboo with a balloon neither floats nor sinks in the tank. It stays in the middle on the 4 gallon tank.
Figure out the weight of the device (ROV, submarine,etc), and then the weight of the water displaced. When they are equal, the device is neutrally buoyant. However, usually engineers create a ROV with a slightly positive or negative bouyancy, personally I perfer a positivly buoyant ROV because if you lose power or the tether is cut the ROV will ascend back up to the top. A more simple answer is that when the gravity & buoyancy are equal it is neutrally buoyant
If the density of an object is 1, it will neither sink nor float in water. When the density of an object is equal to the density of the fluid it is placed in, it will be neutrally buoyant and will remain suspended in the fluid at the same level.
Water affects buoyancy by providing an upward force called buoyant force that opposes the weight of an object immersed in water. The buoyant force is equal to the weight of the water displaced by the object, which determines whether the object floats, sinks, or remains neutrally buoyant. Objects that are less dense than water will float, those with equal density will remain suspended, and those denser will sink.
Buoyancy force is balanced by the gravitational force acting on an object submerged in a fluid. As an object displaces fluid, it experiences an upward buoyant force equal to the weight of the fluid it displaces, which opposes the gravitational force pulling it downward. When these two forces are equal, the object becomes neutrally buoyant and will float at a constant depth in the fluid.
they are neutrally buoyant. they have ballast tanks to achieve this
