Based on similar wacky, fun and educational places around the globe, the extraordinary House of Experiments features three rooms of purpose-built experiments for the ultimate hands-on experience. Visitors are free to wander around as they wish, engaging with anything that takes their fancy, whether it’s a giant bubble maker, electronic insects, dancing liquid or a machine that plays music according to your weight. They also provide what they call Adventures, namely small performances that aim to show different scientific principles, with enticing names like the Centre of Gravitology, Eggology etc. Written guides are available in English and other languages. Open to the public Sat & Sun 11:00-19:00. Groups can book special visits outside these days too.
