Get the coin to move towards you!

  Got this from another website.
  
  Let's see if anyone could explain why it happens.
  
  Materials provided:
  
  1. A clear drinking glass
  
  2. 4 thick coins (something like SG 50 cents coins)
  
  3. 1 thin coin (5 or 10 cents coin)
  
  4. Table covered with table cloth
  _________________________________________
  
  2 thick coins are stacked up on each side (left and right). The drinking glass is then placed on top of the coins, upside down.
  
  Someone slides the thin coin under the drinking glass.
  
  You are to get the coin out, but without jerking the table cloth, lifting up the glass or stick something inside to get this coin out.
  
  How would you do it?

  it is like u move the table cloth very quickly and able to let the vase stays in place. however, u slowly move the cloth and the coin will move with it.

  the glass is balanced on the 4 thick coins right?
  
  just slide the 4 thick coins say forward.
  
  when you do this, the glass on top of the 4 coins will also move forward. then slide until the thin coin is out of the ae covered by the glass.
  
  didn't lift the cup or jerk the cloth
