The study describes the emergence of Sparks within the CSM Pioneer Organization in the late 1950s. The establishment of the Jisker divisions expanded and strengthened the system of out-of-school education by children of pre-pioneer age, who until then had been outside the Czechoslovak Youth Union. In addition to the symbolism and specific activities of Jisker, specific problems are observed, especially the lack of adult leaders, which eventually led to the abolition of this age category at the CSM at the end of 1967.
