  2. What can you change to make the launch consistent?
  3. What revisions can you make to your catapult to get a launch that goes farther?
  4. Where do you need to place your target to hit bulls eye every time?

Answers to Initial Questions...

  1. Almost all the time, had to make a couple of adjustment to get it better.
  2. Putting in a quick release launch system, so we can make our catapult accurate as possible, as well as putting the bungee cords in the same place every time.
