Count Sandini calls himself the greatest "Sand Counter" in the world. Show him a bucket filled of sand, and in a few seconds he will tell you how many grains of sand are there!

Can you devise a (fairly quick) test to prove whether he can actually do so, or if he's a fraud?

As others have noted, the best way seems to be to get Sandini to count a large amount of sand, and then remove a counted amount of grains.  But why do I have to count the number of removed grains?  Let Sandini do the counting.  Of course, don't let him know the relationship between the three amounts of sand that he counts.
