Making and testing home-made glues (pt 2/2)
Jem Stansfield, Dallas Campbell and Dr Yan from the BBC One series 'Bang Goes The Theory' test the homemade glues that Jem made in 13200. They justify their choice of glue for the test, referring to molecular structure. The three presenters then hang from handles which are stuck using the glues to a sheet of plywood suspended over an outdoor swimming pool. The glues were all so strong that the presenters lose their grip before the glue fails. Back in the studio, Jem explains that testing in his workshop revealed that the milk glue was the strongest: stronger, in fact, than the wood itself.
First broadcast on BBC One on 'Bang Goes the Theory'.
Could be used in conjunction with 13200 from this sequence to structure an activity in which students make homemade glues and then test their strength/stickiness. Students can be asked to evaluate the testing method that the presenters use during this clip. 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/
