That hot Saturday we spent mainly on The Liberty Square and on our social gardens. Day started with some exercises with hula hoop. In Wilda young and a little bit older inhabitants of the district were knitting clothes for trees. At the same time on The Liberty Square young scientists gave lectures on their favourite topics. They told us curiosities about brain, bees, physics and dogs. Thanks to Kasztelania Ostrowska association we have tested herbal infusions. There was also a place for someone who likes dancing. The rhythms of swing didn't permit us to sit in our places. We just needed to dance! It was excellent warm-up befor the silent disco.
