I had the idea of that, rather than using tubes as is currently done, and doing mulitple shots, why not use a plastic or high-density foam plate with notches of varying widths cut into it?
The plastic plate would be layed on an aluminum or lead plate of suitable thickness to act as a witness plate, and the central cavity filled with the liquid explosive to be tested.
A cover plate is laid on top, with the detonator placed centrally to the main chamber.
Upon detonation, the shockwave will radiate out into every side chamber, but only those of sufficient width (diameter) to sustain the detonatin front would have a line cut in the bottom witness plate.
Or so the theory goes.
The depth of the plate, and the number and size of the side-chambers that could be used in any one plate, would have to be determined by experimentation.
