The ZOOMers

Complicated contraptions! Rube Goldberg designed inventions that made simple tasks much more complicated. Now you try to create one that pours milk into a glass.


Materials

Materials Needed


  • Different things from around your house. That's the beauty of it! The ZOOMers used vinegar, baking soda, various fishing weights, springs, rubber toy wheels, a drinking glass, 1/2 gallon milk carton, 2 large tables on wheels, a straight-backed wooden chair, and a whole bunch of other stuff.

Instructions

Instructions


  1. Go crazy! Build the most complicated contraption you can come up with that pours milk into a glass.


Did your Rube Goldberg invention take a long time to build? Did you make lots of modifications and changes as you built it? What did you use to build it? Think of another problem you want to solve Rube Goldberg style. Make a design -- it doesn't have to be as complicated as one that pours a glass of milk. Try setting up a row of dominos. When they fall, they could knock over a ball balanced at the top of a folder. Or, a ball could roll down a folder and knock over a balanced soda bottle. Then, test out your invention, make some changes so that it works really well, and send your results to ZOOM! Each week, we'll publish a whole bunch right here.

361 inches of string, 12 pullies, and 6 metal fasteners were the main parts in my invention. It used 1,397 steps, but it still worked!!! It turned on the light switch.
