Step 1Parts needed

Here are the parts you'll need. You may have some, most, or all of these in your own collection; if not, you can get them from Bricklink.com (or Lego's Pick-A-Brick , but they tend to be much more expensive, if somewhat easier). Part names may be different between Bricklink and Pick-A-Brick.
