Rockets blasted off at 3 p.m. on Sunday June 27 at the Johnson County Fairgrounds in Gardner. Members of various Johnson County 4-H participated in the county rocket launch. These rockets will be entered in the Johnson County fair in August. In preparation for the county rocket launch, several members of the Great Plains 4-H club met at the Lackman Library for classes led by fellow member, Zach Nason. At these meetings they learned how to build their own rockets.
