Are progress so far is going quite well we have finished our corkscrew after the first loop. However we are still having difficulty with the first camel hump because of to much inertia making it fly off the track, we are still trying to find a point on the slope were there is enough force for the marble to get over the camel hump but not too much making the marble fly of the track. Something that has been working really well is our first loop, slowing down the marble just enough for it to be able to go round the corkscrew.
