What we're studying:
Friction, gravity, acceleration, simple machines, and force.Our Team Leader's favorite quote:
"Genius is 1% inspiration, 99% perspiration."Why we think we should win:
Because our machine is cool and works very well.Suggestion for next year's challenge:
A machine that opens a door.Favorite Rube Goldberg video:
One fateful Christmas Eve, Santa Clause is delivering presents when suddenly, he cuts his hand! Acting quickly, he decides to build a machine that will apply a band aid to his cut, using all the toys and Christmas decorations he can find. This is the basic purpose and principle our machine is built around. It is the machine that hepled save Christmas!
Our Step List
1.) First, the marble is dropped down the tube at the top.
2.) The marble travels down the tube and then falls into a red cup at the bottom of the tube; the red cup is attached to a wheel from a wooden toy car.
3.) The wooden wheel turns when the marble falls in and weighs the cup down, which causes another red cup with a second marble in it, to tip down and drop the second marble; the wooden wheel is attached to the cup with the second marble in it by a wire.
4.) The second marble then falls from the small red cup into a larger cup.
5.) The second marble falls through the bottom of the cup and moves through a tube and falls into a gift box, attached to the top of the Christmas tree.
6.) The marble falls through a hole in the bottom of the gift box and then into a cardboard tube.
7.) The marble moves through the cardboard tube and then travels into another tube that is made out of ribbon from a Christmas present.
8.) The marble moves through the ribbon tube and then falls into a channel made of cardboard from a wrapping paper roll and travels down the channel across the Christmas tree.
9.) The marble falls from the end of the channel into a cup which is hanging from wooded toy blocks attached by a wire.
10.) The weight of the marble falling into the cup causes the wooden block with a divot in it to tilt. Attached to this block on the opposite side from the cup is a string which is attached to a wooden toy block with a channel that has a third marble sitting at the top of the channel.
11.)The tilt causes the third marble to roll down the channel in the wooden toy block.
12.) The marble then falls through a hole in the end of the first wooden block and falls onto another wooden toy block with a channel.
13.) The marble rolls down the channel in the second block and falls into a hole located at the bottom of the block and onto a third toy block.
14.) The marble travels down the third block and then falls through a hole at the end of the block.
15.) The marble lands on a ramp that is made of toy wooden blocks. There is a toy Hot Wheels car sitting at the top of the wooden ramp.
16.) When the marble falls onto the ramp it hits the back of the toy car and pushes the car down the ramp. The toy car has a band aid attached to the front of it.
17.) The toy car travels down the ramp and applies the band aid to Santa's hand (the balloon) which is at the bottom of the ramp.
