Key Info
• Can you go all the way round on a swing? Clip 3 of 4
• Duration: 05:36
• Jem Stansfield from the BBC One series 'Bang Goes The Theory' continues on his challenge to be the first person to go all the way round on a playground swing. He returns to his scaled down model in the workshop to discuss and test different methods of decelerating the person on the swing safely. He mentions the need for the deceleration force to be applied over the maximum possible duration in order to minimise the force acting. He tests a rotating catch net on the scale model and then on the full size rig. Several improvements are made to improve the safety of the system and then he successfully completes the challenge, being propelled 360 degrees around a swing using a water rocket. First broadcast on BBC One on 'Bang Goes the Theory' in March 2011.

Ideas for use in class
• Could be used with 13192 and 13193 from this sequence (#13192, 13193, 13195), to demonstrate the process of generating and testing a hypothesis. Or as a stimulus when discussing the forces involved in collisions, and car safety features such as airbags and crumple zones. 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/
