procedure TForm1.Button1Click(Sender: TObject);
var
  i: integer;
  TimeSleep: integer;
begin
  TimeSleep := 5; // the speed you want to show/hide.Increase/descrease this to make it faster or slower
  for i := 1 to Self.Height do
  begin
    Self.Top := Self.Top+1;
    Sleep(TimeSleep);
  end;
  // now let's show it again(use this as code as the show code)
  for i := 1 to Self.Height do
  begin
    Self.Top := Self.Top-1;
    Sleep(TimeSleep);
  end;
