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

Nina investigates why bubbles burst with the help of Luke, her sight neuron. Experimenters Eve and Liam visit Nina in her lab and use their senses to work out that bubbles can burst when they touch something, or sometimes just burst in the air. Nina shows that we can't blow bubbles with just water but that adding washing-up liquid to water can make it stretchy.

Then they all go to a pond and prove that bubbles last longer if they land on water. Finally, back in the lab, they have a competition to see if a hot hairdryer or a cold fan will blow longer-lasting bubbles. Show less
