Building the London Eye: Very interesting, but a bit lengthy. Good info on the purpose, planning, and construction of the eye.

Build the London Eye Online: The site goes through the parts of a wheel and how they work together to create the ride. Good information for presenting your wheel and sounding like you know what you are talking about! Good for starting to think about the parts you will need to create. Includes glossary of terms.

Follow these Design Steps
1. Decide how you will construct your wheel...brainstorm...share ideas...use lots of paper.
The best way to have a great idea is to have lots of ideas.
2. Create a final blue print of how it will look.
3. Decide what materials you will need. Make a list. Label the parts of your blueprint with the type of material.
4. Estimate the cost of your design. Put a rough estimate on your blueprint.
5. Consider S.A.F.E. If it is not S.A.F.E. rethink your design.
Carefully Create your Design
Begin to create your design. Put someone in charge of spending. When you buy new materials you will need to record what you bought and the total cost.

Test along the way. If something is not working..STOP...revisit the design and make adaptations. Trial and error will waste your money.
