The Jury were shown a video yesterday of a device made from the substances mentioned, and the effects were discribed as substantial.
So either, the people that put the demo together to be videoed for the court lied. In which case, I'm sure the defence will put that point, and will probably have done thier own tests.
or
That the Crown case that the effects would have been sufficent to bring down an arircraft are correct, in which case, the restriction on liquids have some validity.
Time will tell.
