By any of the following Put rough surface stickers (can be bought) on the surfaces. Increase the surface area of contact ( a cuboid on it's side instead of on it's smaller side) And maybe put a carpet or rough surface between it ( it works reverse of the ball bearings)

What is the source of friction?
Friction is a result of the interactions between surfaces that are in contact, more precisely, it arises from microscopic interactions between jagged natures of surfaces. Friction is present even when an item is not moving.
What opposes motion between surfaces that are touching?
Force of friction
Do lubricant lessen friction?
Yes it does - that's the whole point of using lubricant. It minimises friction between two surfaces.
Is Friction reduced between polished surfaces?
when we polish surfaces, the molecules or atoms of surface come closer to each other so there is no space for fiction so it is reduced but not reduced to zerowe cant reduce friction to zeroWhen we polish a rough surface smoothly,the unequalities gets reduced,therefore friction is reduced
What is the difference between Static and Kinetic Friction?
Between any two body surfaces in contact there acts an frictional force. A friction can operate between a given pair of solids, between a solid and fluid or between a pair of fluids. There are two types of frictional forces : kinetic and static friction. When two bodies in contact move with respect to each other , rubbing the surfaces in contact the friction between them is called kinetic friction. The directions of frictional forces are such that it opposes the relative motion. Friction forces can also act between two bodies which are in contact but not moving or sliding with respect to each other. The friction in such case is static friction.
Does overpolishing of surfaces increase the friction between them?
No it does not. It will actually reduce the friction between them.
What two factors that affect the amount of friction between two surfaces?
The magnitude of the frictional force is directly proprotional to the normal reaction between the two surfaces.(2)Magnitude of the frictional force is independent of shape and area of the surfaces
State laws of limiting friction?
1. the direction of force of friction is always opposite to the direction of motion.. 2. the magnitude of limiting friction depends upon the nature and state of polish of the two surfaces in contact and acts tangentially to the interface between them.. 3. the magnitude of limiting friction 'F' is directly proportional to normal reaction 'R' between the two surfaces in contact.. 4. the magnitude of limiting friction is independent of area and shape of surfaces in contact as long as the normal reaction remains the same..
Is it possible for the frictional force between two surfaces that are extremely smooth and flat to increase?
Yes the application of a load normal to the plane of the smooth flat surfaces will increase the friction between the surfaces.
What is the effect of surface area on friction?
The increase in One increases the Other. What alters the friction effects between Surfaces is another matter.
When might you want to increase friction between two object?
Turning wheels against surfaces would require some amount of friction.
Does a smooth surface reduce friction?
There is more friction between the surfaces of 2 smooth surfaces than one smooth surface because there is more surface area.
Explain why the frictional force between two surfaces increases?
There are basically two ways to increase friction between two surfaces, which are, make them rougher (increased co-efficient of friction) or press them together with greater pressure. In either case, you are increasing the interaction between irregularities on the surfaces. Completely smooth surfaces would, in theory, be frictionless.
How can increase the magnitude of friction between two surface?

What is the science behind friction?
Friction is a force of resistance between to surfaces/layers/etc sliding together. Friction converts kinetic energy into heat if the surface is rough then the friction increase did u know that.
What is the friction that exits between a surface sliding on another surface is called?
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
What is the force when two materials rub together?
The force when two materials rub together is called friction. Friction is a resistive force that opposes the relative motion or tendency of motion between two surfaces in contact. The magnitude of the frictional force depends on factors such as the nature of the surfaces and the force pressing them together.
