Experimenters Poppy and Sugar visit Nina in her workshop and discover that the foundations for floating houses need to be built in a special way. Next, they visit some real floating houses in Ijburg in the Netherlands to find out how really heavy things can float. Finally, they do an experiment that explains why floating houses stay steady in the water.
