Balis-Kit

Balis-Kit is literally a ballistic kit to assemble and calibrate. This Small desk catapult is able to provide non-lethal kinetic energy to an object willing to fly. The interest of this kit lies in the fact that you can adjust :

• The power by using different types of elastic or different position of the elastics along the arm
• The trajectory angle by changing the position of the arresting screw
  (See post printing section)

By assembling this project you will gain access to an interesting experimentation tool to discover:

• Physic through elastic potential energy and kinetic energy of the projectile.
• The art of desk war strategy
• Not to forget the ballistic equations with second order polynomial that comes with Newton’s law

For the propulsion you can use different types of elastics.

You will need

• 10 M3 screw 30mm long for the maximum.
• 12 M3 bolts
• Elastics
• Gum makes an intresting projectile.

=================== !!! WARNING !!! ===================
Please send soft material like gum. Metallic material are interesting because of their density but they might break things or hurt people.
