1. Nothing is perfect
2. what about if u put a bit of side on ;p........
3. "Goldilocks Hit"...gonna remember that next time I blaze one
4. I thought better one. we may try this idea on building ellipsoid shaped room in which two audiences placed right over focus points. talking even whispering something on focus point could be easily heard by the one on the other point.
5. 2:25 Kudos to the director for keeping the shot until the ball went in
6. goldilocks hit would like to hear Ronnie use this expression
7. He is no Ronnie o'sullivan
8. You also have to factor where on the ball you hit it because it'll spin differently. To much on the bottom will make it spin back towards you, to much on top will make it roll forward even after hitting something, to much left or right will curve it
9. Then u apply a little right english, none of this will matter
10. THIS IS AWESOME!!!!!!!!!!
11. Price?
12. So am I right by saying for moons and planets to survive they have to fall into the perfect ellipse otherwise they will eventually hit a star (the hole)
13. Your vest is make this illusion or something...
14. Some Euler's Disk action going on when it's going in the hole 2:25
15. Wait what...?
16. that's cheating.
17. In real pool, rebounding is not a perfect reflection off the surface (i.e. Like with a light beam) due to the deformation of the bumper when the ball strikes it. This is conpensated for by using a more extreme angle than you might expect.
    His mathematical ellipse table would only work if he keeps his strikes soft, and had very stiff bumpers.
