As well as all the usual indoor excitement, like a brand new explosive live science show and the unforgettable Planetarium, families will be able to enjoy festival tents, mini stages and live science outside in stunning landscape of the South Downs National Park. And it’s all included free with admission!

In the Bio:Space garden nature sounds amazing! Here families can take part in the Music Makers tent by building a sound maker and replicating the beautiful noises of nature. There will also be an opportunity to learn more about the sounds we hear around us every day. Next to the Music Makers tent is the Star mini stage. Here children can become the stars by putting on a performance with their hand-made music makers.   

Boom, Bang, Fizz – the science of fireworks
