EOSC Ice Breakers are discussion cards developed under the EOSC Future project for trainers on EOSC-related topics and Open Science, as well as for all those who would like to learn more about these topics. The playing set consists of a card deck including 30 cards: 8 mythbusting cards and 22 statement cards, and playing instructions. The cards can be used in many ways, e.g. in engagement and training activities.
