Do you love experiments? In this puppetry and science video, Vinny the Vulture will discover how you can easily tell which of the many liquids in your house is a base and which is an acid. And how to get a cool colour-changing effect when mixing them! What do you need for this? Smelly chemicals or mysterious potions? No, just red cabbage juice (ok, it is a bit smelly!). Join Vinny in this household experiment! Adult supervision advised and the activity is suitable for children aged 8 years and up.
