    Our Step List

    (1) A person pushes a row of dominoes, which (2) hits a toy car that (3) pushes a golf ball through a paper cup, making it roll down the ramp and (4) fall on to the lever. The golf ball then slides down the wedge and (5) hits a row of four golf balls. The golf balls fall down the inclined plane/track and (6) hit the book, which (7) pushes two duct tape rolls off the box. The duct tape rolls (8) push the basketball, which (9) pushes the second book over. In turn, that book (10) knocks the brick down, which has a string holding a skinny post hooked on a chain. The (11) string falls with the post, taking the chain off the post and making it slide down the pipe and hit (12) the metal plate/scale on the pulley. The weight and momentum of the chain (13) makes the metal plate fall, sliding (14) the magnetic eraser up the board and erasing it.

    (1) A family [dominoes] is going onto a trip for Halloween when they got a call from the substitute at school. They run to the car and trip, (2) making their car go forward and (3) dislodge a boulder [golf ball]. The boulder (4) falls down a hill [track], falls onto a see-saw [lever] in a school playground, then (5) down a rock climbing wall [wedge], scaring kids [four golf balls]. The kids go down a slide where they (6) accidently slide into the principal [book], (7) knocking over school supplies [tape rolls]. The school supplies (8) knock into the office lady [basketball] who (9) tackles the vice principal [book].. The vice principal (10) trips onto a short mechanic [brick], who gets shocked and drops (11) his tools [the chain] down a ventilation shaft [pipe]. The tools (12) fall onto the substitute’s head [metal plate/scale], and he (13) instinctively reacts, causing him to (14) erase the board he was working on.
