Science is fun, but fun is not rocket science. Come and have fun in the first Czech science centre, iQpark in Liberec. Hundreds of interactive exhibits await you spread over four floors, moving, lighting up, humming and literally urging you to play whilst learning about the laws of nature. At weekend, you will see a specially prepared science show, based on experiments with a Van de Graaff generator, with liquid nitrogen or with gases. On Sunday, you can make your own perfume. Mix a fragrance from eleven essences to precisely suit your requirements or to give as a gift to a loved one and take it home in a small flask with an atomiser as an unusual souvenir from your trip.
