One of the biggest obstacles facing electric vehicles is their range — the best models on the market can only drive about 100 miles on the highway on a single charge, which is pretty limiting in a world with very few EV charging stations. But AAA, the biggest roadside assistance service in the country, plans to offer a solution that has helped many a stranded motorist who runs out of fuel: An emergency supply of juice.
Now that looks like fun. Of course we intuitively know it's completely fake, and involves the usual videographic sleight of hand, but let's apply some basic physics to the situation to check our intuition.

While the principle is fairly straightforward, this video is such an endearing representation of the concept of relative motion that we had to share it. Who wouldn't appreciate the lengths they went to do the demonstration, not to mention the dramatic atmosphere of the video!
How can something that appears to defy the laws of physics follow them so perfectly?

The counterintuitive demonstration in the video is a beautiful example of the concept of center of gravity. It sure looks like the fork and spoon should immediately teeter off of the glass and crash onto the table. And its even more dramatic when half of the matchstick burns away but the contraption still balances on the edge of the glass. But its all physics.
