So hyped up with chemical potential energy, you find that you are each able to run at 1/2 the speed of light (0.5c - This is going to be an interesting game of laser tag!) Early in the game you find yourself chasing your friend, with you running full out at 0.5c and your friend jogging along at 0.2c. Seeing your chance for the easy score, you fire your laser at your friend.
