Hello, my name's Carol and, amongst other things, I'm a scientist, a STEM Ambassador, and for the October half-term I was a volunteer Science Busker for the Manchester Science Festival. You may have seen me, and fellow buskers, in Piccadilly Train Station, the Trafford Centre, or out and about in Bolton. We had lots of different hands-on puzzles and experiments for you to try out. One of them was the *straw oboe* - a simple but effective demonstration of sound, vibration and pitch changes. All you need is a plastic straw, a pair of scissors and a lung full of air, and with a bit of practice, and a few friends, you can create your own straw oboe band! To check out me and an enthusiastic festival-goer trying out our straw oboes, watch our little You Tube video. For more information about some of the busking experiments that you can try at home now the Festival's over go to Try this at home page of the Festival website.To find out more about becoming a STEM Ambassador, where you will have the opportunity to volunteer for the 2010 Manchester Science Festival, visit the Stemnet website.
