I want to make a small model rollercoaster for a science research 
project.  My biggest design problem so far is figuring out how to get the 
car (or ball) up the first hill.  After that, momentum will carry the 
object through a simple ride, but how do I get that object to the top?  
I'm thinking that I could build something with cranks and pulleys.  Any 
ideas?
