Key Info
  • Making music using a cattle grid Clip 2 of 2
  • Duration: 04:09
  • Jem Stansfield and Dallas Campbell from the BBC One series 'Bang Goes The Theory' test the custom made 'cattle grid' that Jem has made by welding over two tonnes of steel over three long days. The metal ladders are fixed to a length of disused runway and then they discuss the correct choice of vehicle for the test. They need a speed of 45 miles per hour and want to avoid using a standard car that would always have two wheels on the cattle grid at any one time, so they choose a Reliant Robin which has one central wheel at the front, to act as the stylus on a record player. The test works, and Dallas is able to recognise the Bridal March music generated by driving the car over the cattle grid. First broadcast on BBC One on 'Bang Goes the Theory'.

Ideas for use in class
  • Could be used in conjunction with 13206 of this sequence, to illustrate the generation of sound by vibration and to provide a novel context to the applications of sound. Students could research reports of opera singers shattering glass using their voices and evaluate the evidence to support these reports. This clip accompanies a BBC Teachers' Pack to support Series 3 and 4 of 'Bang Goes The Theory'. The pack can be downloaded from bbc.co.uk/schools/teachers/bang/
