Experimenting with watercolours

I wanted to create a marbling effect so I tried this easy way which a friend told me about. All I had to do was fill a sink with bubbles and splash watercolour on to the top of the bubbles. I then placed my sheet of paper on the top and this is the effect I got. I am really pleaded with the outcome and will use these within a collage, the colours will really make it stand out.
