Our machine is the embodiment of women's achievements throughout history. We selected women we admire and highlighted their achievements through the magic of Rube Goldberg. Come on a journey as Florence Nightingale checks on soldiers, Marie Curie receives her Nobel Prize, Bessie Coleman goes from cotton fields to flying planes, Rosie the Riveter inspires women to take on the industrial workforce, Sally Ride blasts off into space, Sandra Day O'Connor becomes the first female in the Supreme Court Justice, and Serena Williams fights for equality in payment of tennis athletes.
Our Step List
1. Lamp is pulled up
2. Ball, sitting on a lever, is knocked down a ramp
3. Ball turns sad faces happy (the ball is turning "L" blocks to proceed down the ramp)
4. Ball goes into a basket (part of pulley mechanism) pulling it down
5. Wood plank on the other side of pulley goes up and turns a wheel
6. Wheel releases our Nobel Prize (pendulum).
7. Nobel Prize knocks a wedge
8. The wedge pushes our "plane" down the plank
9. "Plane" rolls to hit a wooden lever
10. The lever knocks into a string which is held in place, this releases our our cotton/cloud up
11. The cotton/cloud knocks into a plane resting on a ledge
12. The plane goes down the zip line and turns the gear below
13. Wooden plank attached to gear knocks over wooden pole
14. The pole then triggers the mouse trap (launches the rocket ship)
15. Mouse trap releases the washer connected to the weight
16. The weight falls onto air pump; pushing air through the tube
17. Air through the tube launches the rocket across the table (through space)
18. Rocket hits Sandra's gavel
19. The gavel then hits Serena's tennis ball (while she serves)
20. Her tennis ball swings down and hits the foam tube
21. The foam tube hits the jumbo craft stick
22. Then the jumbo craft stick hits the coin
23. Coin rolls down the shaft into the piggy bank (signifying equal pay between men and women)
