Zebra Man has piano lessons, but he doesn't like them at all so when his piano teacher leaves the room to read a magazine(or something like that) he sets up a contraption that plays the piano,so he can trick the piano teacher into thinking he is playing,while he bolts out of there. Steps: (A)Green flag is pressed(B)Car rides up the ramp(C)Car hits soccer ball(D)Ball falls onto pulley with ax(E)The sudden momentum of the ball makes both the ball and ax fall(F)Ball and ax falls onto seesaw(G)Ball and ax makes the seesaw unbalanced.(H)Seesaw goes from one side to another and hits piano.(I)You get a nice song to hear.
This Rube Goldberg was made to play a piano(Warning:If you try this at home someone might get hit by a ball or an ax.) Rube Goldbergs are made to do a simple task using complexity,but it's made mainly..................................................TO ENTERTAIN!! Simple Machines: Incline Plane(ramp) (not an airplane),Pulley(maybe use this if you need to play a piano),wheel and axle(car) (cool,soooooo... what is that?),a lever(seesaw) (I think your seesaw is bent) ,and finally a wedge(warning:don't touch the ax)
