How to Blow Out a Candle
By Kendall
My Rube Goldberg machine goal is blowing out a candle. A Rube Goldberg machine makes a simple thing like blowing out a candle harder than it really is by putting several simple machines together to make one big machine to get the result. My machine has at least three forces and it has at least five different simple machines. Each step on my machine has at least one simple machine in it except for the last one, which only has a force. I have at least one of Newtonfs laws in my machine.
Here are the steps of my machine in order. First, the ball rolls down the incline planes inside a little house, which makes the ball one of Newtonfs laws. The ball hits a lever that makes the dominoes get started pushing each other down until the last domino hits a bungee ball, which is a spring, and it makes the bungee ball fall down off the table and land on a lever which makes the other end of the lever fly up and hit the back of a skate, a wheel and axel. The skate rolls down an incline plane and hits the paper cutter, which is a lever, and cuts the string that is attached to a bag of rice on each side of the pulley. On one side of the pulley the rice was heavier so the other rice bag falls down on a pumper which shoots air out and blows out the candle.
Those are the steps to my Rube Goldberg machine. The incline planes, pulley, spring, levers, wedge and most importantly, force all work together to make the machine work. The force is most important because if there wasnft gravity, the ball at the beginning of the machine would be floating in air and none of the machines would have worked. I think the Rube Goldberg machine project was hard, but fun.
