- This bowling ball can get you a strike every time,
because after you bowl it,
you simply lean in the direction you want the ball to turn.
This idea has been on my bucket list for over three years,
so today I'm gonna tell you how we made it,
how exactly it works,
and what happens when you take it bowling
but neglect to tell the people you're bowling with
about your slight advantage.
- Oh.
- So this trick ball looks and feels like
a normal bowling ball,
and that's because it's made from a real bowling ball.
Step one on this project was to harness my inner
Lincoln and Dan to see what's inside an actual bowling ball.
The first thing we discovered is that they aren't symmetric.
That means the center of mass
isn't at the actual center point of the ball.
I won't get into physics here,
but this is one factor that helps the pros
curve the ball as much as they do.
Next, I had my buddy Mark, who owns a machine shop,
hollow out the ball using a lathe.
Once that was done, we were left with two shells
and now I just needed to fill it
with some engineering magic.
And to do that, I need to get myself to London
with a trustee four second travel montage.
