Step 1 •

Person will push the tape roll down.

Step 2 •

The roll of tape hits the weighted wagon which will roll down and hit the car.

Step 3 •

•

The mini car is let go and it hits the roll of red ribbon. Make sure ribbon is set on the exact spot right before it could roll down the ramp.

Step 4 •

•

•

The roll of ribbon rolls down the ramp and hits the yellow blocks that are arranged like dominoes. The blocks are arranged starting from left to right: 1” 1” 1.5” and 2” The yellow blocks tumble down to hit the final red blocks.

Step 5 •

•

Final red blocks are hit. Red blocks are connected to a string that suspends the back wheels of the weighted car. The red blocks are arranged perpendicularly to each other with the last of the three pieces being opposite of the bottom two. The last piece is weighted so that it will fall.

Step 6 •

•

The weighted car is released because the fallen red block pulls out the string. The weighted car runs down the ramp and hits the tower of yellow blocks stacked on top of each other.

Step 7 • • •

The tower of block is suspending the pendulum ball. Make sure the string is tense. The blocks must be arranged on top of each other so that when it collapses, the pendulum falls straight down and directly knocks toward the cup.

Step 8 • •

•

The cup full of marbles is knocked down. The cup is slightly tilted before so that its easy to knock down. The cup is stuffed so that all marbles will fall out of the cup.

Step 9 • •

The marbles roll out of the cup The marbles roll down the slide

Step 10

•The marbles roll into the cup.
