Okay, here’s the deal.
You’re in a car going forward at 100 km/hr. You’re finished with your (glass) bottle of lucozade and naturally you just want to get rid of it by throwing it out the window. But you’re not a complete muppet; you would prefer if the bottle didn’t actully break upon impact.
So in what direction and at what speed should you throw the bottle?
Hint: Scroll forward to 3 minutes 50 seconds of this cool, cool video (unfortunately this site doesn’t seem to accept video embedding from this site).
Now I know that videos are no substitution for the real thing, but I think in this instance we can make an exception.
