Ola lived in a small town and really enjoyed playing on the playground near her house. One day she took her best friend, Tymek, there. When they got there, they saw something strange. Next to the swing was a big silver rocket, which they had never seen before! The rocket was shiny and had coloured buttons on the door. Ola moved closer and touched the door. Suddenly it opened by itself! Inside there were lots of lights, levers and colourful screens. Timek bravely went in first and Ola followed right behind him. Suddenly, a voice appeared above their heads: - Welcome aboard! Are you ready for an adventure? The children looked at each other with wide-open eyes. In the middle of the cabin was a large blue button that gently pulsed with light. Should they press it? What would happen if they did? Ola stretched her hand towards the button and Tymek grabbed her hand. All around them lights began to flash and the deck shook slightly. At the same moment they heard through the loudspeaker: - Prepare for departure! Will the children press the button and set off into the unknown? What awaits them beyond the playground?
