    What we're studying:
    Simple Machines

    Why we think we should win:
    I think we did a really good job because we spent a lot of time on it. We worked really really hard on it and spent time after school and during the school day. I like our invention. I think the track was pretty cool and I think the LEGO part was pretty awesome. I like our technique for blowing up the balloon. Our theme was clear and our invention creative.

    Suggestion for next year's challenge:

    Welcome To Toy Land

    Our Step List

    Toy Land the Rube Goldberg machine!

    Step 1:You put a marble in the marble track. The ball rolls down the marble run that acts like a screw. Gravity makes the marble roll down the track.
    Step 2:The marble gets shot out of the end of the screw from a ramp and hits some dominoes. Then the dominoes fall down in a chain reaction over each other.
    Step 3: The last domino falls onto a golf ball and pushes it down to the checkerboard shaped as a double sided incline plane.
    Step 4: The ball falls into a wedge shaped gated area using Zookers which have suction cups on the bottom of them so they stick. The gated area is on top of a checkerboard which is at an incline plane. Gravity makes the ball get pushed down the K’nex bridge.
    Step 5: After the golf ball rolls down the K’nex bridge it hits a rubber ball like Newton’s cradle so it can make the rubber ball accelerate at a slower pace than the golf ball.
    Step 6: The momentum of the rubber ball slows down and hits a toy train.
    Step 7: The toy train rolls down a track and hits a baseball.
    Step 8: The baseball rolls down into a baseball glove and comes out of the glove and rolls down a wire from the force of gravity.
    Step 9: Then the baseball rolls down and lands on a car track,then rolls down that and lands on another track.
    Step 10: The baseball hits a cone activating it to slide down an incline plane.
    Step 11: The cone hits a different kind of jump that is behind the bottle in a holder. The bottle has vinegar in it with a balloon that has baking soda in it and is attached to the bottle.
    Step 12: The balloon falls over causing a chemical reaction and emits carbon dioxide to make the balloon blow up.
    Step 13: Since the balloon is blown up, it pushes a lever causing a truck to roll down an incline plane.
    Step 14: The truck pushes a lever that activates a flat surface to incline as a rubber ball rolls down it.
    Step 15: The rubber ball rolls onto a platform and pushes a lever with a needle on it a koala bear holding the needle gets pushed down into the balloon popping it.
