You asked for it - and it's finally time! Definitely one of our most requested videos: volcanoes! Why and how they erupt, what magma and lava are and how volcanoes can shape our landscape. We'll also show you step by step how to make your very own erupting volcano with a chemical reaction at home!
You'll need: a table cover/something to protect surfaces, large piece of cardboard, plastic bottle, flour (for papier-mâché), salt, water, masking tape (or sellotape), scissors, various paints, paint brushes, white vinegar (or any kind), Bicarbonate of Soda, washing-up Liquid, food colouring.
There's also a bonus experiment you can try to make an even BIGGER volcano - you'll need Diet Coke and Mentos.
These are suitable for ages 8 and over and require adult permission and supervision. Watch on YouTube.
