Air Hockey

Air hockey is a game where two players play against each other on a low-friction table. Air hockey requires an air-hockey table, two player-held strikers, and a puck.

An air hockey table has a very smooth and slippery surface which reduces friction by suspending the puck on cushion of air, so that this its motion is much less altered by friction, causing it to glide in a straight line at relatively constant velocity across the table.
