Parts List
Please note that when constructing multiple rockets, some parts on this list will be part of a unit purchase. For example: #10 washers with a quantity of 4 is called for but it makes more sense to puchase a bag of 50 washers at one time. Larger, bulk purchases will reduce the per unit cost of a launch pad.
All parts can be found in the hardware store with the exception of the spring. If the hardware store doesn't have a suitable compression spring, then order them from the supplier listed. The spring cost is a high estimate because the spring chosen is not the best for the job.
