Science Bob is mad about science and he loves telling kids how great it is. His brilliant science website is full of videos and simple instructions on things you can do with that bottle of stuff you found at the back of the kitchen cupboard. Here he shows you how to make your own bubbles in a bottle, or lava lamp as your dad might call it.
This is one of many simple science experiments to be found in Make and Do Science, in which you can also learn how to make giant bubbles, write with your own invisible ink and make a volcano erupt!
