Putty Blasting Grounds

Charge:

A 1 cubic centimeter (20mm x 10 mm x 5 mm) charge of
acetone peroxide putty,
binded with dinitrocellulose dissolved in acetone.
Using a drinking straw filled with black powder as a fuse.

Charge and plate (side of computer feed, 0.5 mm thick) are buried
together at a depth of about 20 cm,
with the charge slightly taped to the
side of the plate to keep it in place during burial.

As you can see, the plate is severely deformed.

===============================================================================

Second test is performed with the same kind charge, and also buried,
but
now using HMTD putty and a cup behind the plate to encourage the formation of a
hole.

As you can see in the pics ... it worked :-)

The hole has the exact same shape as the cup (got deformed too).
And to
think this was all caused by a massive amount of air pressure in the kilobar
range ...
