2. The Design Manually begins with a billiard ball
Billiard ball falls on cloth, cloth projects marble
Track leads to mousetrap, marble sets it off
String secured to mousetrap removes tape that releases two strings:
One that releases the car
One that releases the additional weight needed to lift the kg of mass

3. Stored energy Starts at a raised position
Mass of billiard ball raises lesser mass of the marble
Marble gains energy through angled ramp toward mousetrap
Mousetrap is engaged and pulls tape
Tension is eliminated in the strings
Extra weight, car, & polar bear roll down ramp using gravity and pulls weight

4. Construction issues Beginning stages Application of ideas Gate
Mousetrap
Lifting kilogram
