Launcher war!

Today at Clear Spring School the high school kids had their physics class launcher war, in which their projectile launchers were aimed at each other's and the fight was to the finish. It was a fun culmination to the project. I had to leave for Little Rock before the war was finished so I will find out later who won. Easton's very well made launcher was great for long range. Mine shown below, had the advantage of throwing our disk shaped projectiles so they would roll upon landing. It was still in contention when I left with a volunteer using it in my place.
