They could have moved the block through water, which would be Fluid Friction, and makes it easier to move.
It seems that they 'wet' the sand with water. Not too much but just enough.

Friction is the act of one surface rubbing against another. To reduce friction, use something that offers a small amount of friction. Smoother substances reduce friction. A way to reduce friction is to use something which offers a small amount of friction. For example, you could use something like plastic or glass. Water, most liquids and different types of oil reduce friction. Powder, oil and grease are used in between surfaces to also reduce friction.
No, sand does not reduce friction but increase friction.
Lubrication to reduce friction. To increase friction step on the brakes.
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
Reduce the friction . . .Apply lubricant to the surfaces in contact, or reduce the mutual pressure.Friction the reduce . . .The phrase has no physical significance.

yes because when they brake the friction is caused to reduce

I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
Oil makes things "slip", it is a lubricant, it reduces friction. Brake blocks work by "gripping" the wheel rim and stop the wheel turning using high friction between the block and the rim. Placing oil on the brake blocks will reduce their efficiency and if the rider can not stop quickly they may run into things.
the factors that reduce in case of friction are the velocity and acceleration.
Oil is used to reduce friction.
