Weigh the item down or find a way to fill it with water. For it to sink it must have a greater mass than the liquid it is placed in.

Things sink or float in oil based on their density. Objects that are less dense than the oil will float, while objects that are denser will sink. This is due to Archimedes' principle - an object will float if the weight of the fluid it displaces is equal to or greater than its own weight.
Objects float or sink based on their density relative to the fluid they are in. If an object is less dense than the fluid, it will float; if it is more dense, it will sink. This is due to the buoyant force acting on the object, which is the result of the pressure difference between the top and bottom of the object.
Some things float or sink based on their density. Objects that are less dense than the liquid they are placed in will float, while those that are more dense will sink. Additionally, the shape and size of an object can also affect whether it floats or sinks.
Because of the objects density.
The density of an object determines if it sinks or floats. If an object is more dense than the medium it is in, it will sink. If it is less dense, it will float. Therefore, the most dense things typically sink.
