Cruise ships love to show off their outrageous amenities, but how do they offer billiard tables to their guest on the high seas? Every small wave would move the balls and ruin the game. To fix the problem, genius engineers created a gyroscopic pool table.
Every second, computers alter the table to keep it perfectly level. It may seem like the table is uneven, but really the boat is moving and the table is staying level on a perfect plane. Look closely.
The video comes from the cruise ship “Radiance of the Seas”, travelling from New Zealand in rough weather in December 2011.
