Scientist Nina and her young experimenters discover the amazing ways that things can change and react in the everyday world.

Nina investigates why jam is so sticky with the help of Felix, her touch neuron. Experimenters Ben, Nathan and Patricia visit Nina in her lab and get sticky with some jam. Then they have a food race and discover that some foods are runnier than others and that jam is too thick and sticky to be runny. They all go to a jam factory to see jam being made from fruit and sugar. Finally, back in the lab, the children do an experiment with sugar and water to prove that it's the sugar in jam that makes it so sticky! Show less
