Firing the catapult
1) Swing the swing arm to the firing position and place the release arm under the ratchet.
2) Make a small clay ball and place it in the spoon.
3) Aim the catapult and pull the string ~ stay to the side so the swing arm doesn't hit you!
Some things to consider:
• The strings will stretch over time and will need to (but not too tight! ). Do this when needed.
• When not in use, release the tension in the catapult so it is not under load.
• As a neat math and graphing experiment, roll up some aluminum foil into a loose ball. Fire it 5 times and record
the distance, then calculate the average distance. Squish the ball a bit tighter, then fire it again, record the
distance and find the average. Do this a few times and then graph the results. Why do you think the distance
changed!
• The clay that comes with the kit needs to be stored in the package when not in use so it doesn't dry out.
• Dressing up like Leonardo da Vinci, presenting the catapult as a show~and~tell item in school or at work will
make you 23% more popular (if that is important to you).
