The Institute of Physics Teacher Network has run rocket and dragster launcher makeand-take workshops for some years. This article sketches out the origin and development of the workshops, how they have spread the original idea, and how that idea has developed and the design of the launcher changed. Finally, some examples of use are given. The whole is presented as an example of how the right sort of "one-shot" professional development sessions can have a widespread impact through a centrally coordinated network of local support.
