How do we hear sounds? What is music? How does a microphone work and what magic is behind record players? These questions and many more will be answered by Alheimur at the Big Bang festival this year. In addition to fun knowledge regarding sound and soundwaves the children get a chance to let their voice be heard by answering the question “What fascinates you the most about science?” And who knows, maybe you get the opportunity to put a white lab coat on and be a scientist for a moment. See you there!
