Animated Rube Goldberg

I wish Rube had seen one of his drawings come to life the way it's animated in this app... Very cool.

Very cool...

I'm not one to write reviews on things, but this is really a neat app. lots of wonderful photos, great animations, and more than enough information about how machines work. Kids will love this... maybe a lot of parents will too. Time to find me a simple lever.

Fun look at basic science

Great app--it makes some complicated ideas so easy to understand with pictures and animations that are also just plain fun. Loved the Rube Goldberg contraption. My kids played with that over and over.
