The twinkling is caused by the atmosphere disturbing the light as it’s passing through.
When a star is low to the horizon, the angle means it has to pass through much more atmosphere before it gets to you. Therefore there will be more disturbance, and more twinkle.

The twinkling is caused by the density of the air in the atmosphere , the light of the star ,to see the light of the star, has to travel much distance to reach our eye sight, so in this travelling region by the air , the light will scattered nd it looks like twinkling
