What we're studying:
Simple machines, and inventors: Rube Goldberg, Thomas Edison, Richard James (Slinky), and James Dyson (vacuum cleaner)Our Team Leader's favorite quote:
Measure at least twice, cut onceWhy we think we should win:
We spent a ton of time on our machine, learned a lot, worked well together, and had fun. Suggestion for next year's challenge:
Somehow use water, such as pouring water. Or, somehow use a catapult.
Welcome to the KCC CONTRAPTION!!! We’re excited for you to see this cool Rube Goldberg Machine. Our machine is all about simple machines. We use all of them--inclined planes, wedge, screws, a lever, pulleys, and wheels and axles. We also studied some engineers: Thomas Edison, Rube Goldberg, Richard James (Slinky), and James Dyson (vacuum cleaner). And, we used a flying pig, duck and fish. We had a lot of fun, worked together, and accomplished what we set out to do.
Our Step List
1. Welcome to the KCC CONTRAPTION!!! We’re excited for you to see this cool machine. Our Rube Goldberg Machine is all about simple machines, and starts with the Slinky. We use our hands to start the Slinky slinking down the stairs. We built the custom Slinky stairs ourselves, and can sometimes use homemade tongs to start the Slinky.
2. The Slinky hits a ball bearing and lands in a fish net laying across and on top of an oil funnel.
3. The ball bearing falls through the oil funnel and hamster tube and slightly spins a hamster wheel--a wheel and axle!! No hamsters were hurt in the making of this machine. If this misses, then the force of the Slinky pushing on the net will pull a string.
4. A string attached to the wheel goes through a pulley mounted on a clothes rack and yanks a piggy bank balancing on top of the clothes rack.
5. The piggy “flies” and “falls with style” into a plastic basket. The piggy bank contains some pennies, and the basket contains some other weights. The weight of the piggy bank landing in the basket pulls another string that is connected to a piece of wood that is holding back a croquet mallet.
6. The piece of wood acts as a door, and when pulled with the string, allows the croquet mallet to swing. The mallet swings because it’s mounted to a castor wheel, and gravity causes it to rotate downward.
7. The croquet mallet swings counter-clockwise and hits a golf ball positioned on a wedge-shaped platform.
8. The ball’s potential energy is converted to kinetic energy as it rolls off the wedge and down an inclined plane.
9. The golf ball hits a toy car (wheel and axle) at the bottom of the ramp, pushing the car into a funnel. We call this the black hole because it’s made from black plastic, and there's a hole inside. The car fits through the funnel’s hole, but the golf ball’s size prevents it from going through.
10. With gravity, the car presses a cardboard platform, beneath which is a large ball bearing. The ball bearing is released and rolls down another inclined plane, and another.
11. Before it falls off the machine, the ball bearing is attracted to a magnet that is attached to a string. On the other end of the string is another magnet, which is acting like a trap door that's holding back another golf ball. The weight of the ball bearing attached to the bottom magnet causes the top magnet to release from it's position.
12. The golf ball is released and rolls with gravity through a dust collection hose. The ball exits at the bottom and triggers a rat trap fastened to the machine with wood screws—another simple machine. We used a lot of screws in making our machine.
13. The rat trap pulls a string that wraps around the clothes rack and is attached to a little yellow rubber ducky. Did you know that rubber ducks could fly?! That really quacks us up.
14. The rubber duck falls and hits a book, starting a domino effect. The books are all educational books about science and inventors, like Thomas Edison, one of the inventors of the incandescent high resistance electric light bulb.
15. The book dominoes then hit a tennis racket, which then hits a bowling pin. The falling pin presses down a lever (another simple machine) on our catapult.
16. The catapult launches a small red potato through the air and into a PVC pipe.
17. The potato rolls down the PVC pipe and falls into a homemade chute made of a cut PVC pipe, propped up with a plastic watering can in the form of a pig. The chute acts like another inclined plane.
18. The potato rolls down the chute and hits a baseball. The baseball then has a measured roll into the end of a tape measure, hooked on the leg of a table.
19. The tape measure springs quickly back to its base, which is attached to the backboard of our machine. The vibration of the tape measure causes a wooden fish propped on the backboard to fall off. The fishing pole helps hold up the fish.
20. The flying fish lands on top of a medicine ball that's propped on top of a portable stand for some hand-weights. This is our home gym. The medicine ball rolls down a home-made PVC ramp, gaining momentum.
21. The medicine ball rolls off the ramp and onto the floor switch of our lamp, turn off the light.
And this was our Rube Goldberg Machine! The KCC Contraption!!

Our Machine Verbal Presentation. This is your team’s chance to shine and be creative! We want to hear the story your machine tells, and understand how the steps represent the theme and key elements of your narrative. The Machine Introduction should not be a step-by-step explanation of how the steps work. This is where your personality, humor, and team spirit engages the audience and gets them excited to see your machine.
