Take 2 forks and place them on one another in such a way that we can place the coin in between the prongs. Now try to place the coin with forks on the edge of the glass. It will take you some time to adjust the coin on the edge. This requires a little practice to adjust the coin on the edge of the glass. With a little effort, we will see the coin sitting on the edge calmly. If you look closely you will see it wobbling a little bit. The mass is in the handles of the forks so as a low center of mass it stables as it looks.
