HI , Still don't see the grooves extending through the edge of the glass as can also be seen in the second 1 illustrated , those grooves as shown in the video held the top plate off the glass cover/detonator switch using twigs. keeping all pressure off the internal glass plate till stepped on. Peter.
Glass mine. Yikes! Never heard of that before. Thanks Pamela.
Hmm, possibly the grooves in the glass mine in the video might be "break here" lines, like the grooves on the American-style pineapple grenades, the better to fragment and slice up the enemy (or
any unfortunate creature that wandered by. Do you know where your kids are?).
I still can't get over SAVOR tho. What's that all about? "savor the carnage with our new line of SAVOR GLASS MINES"??
It
has to be kitchen glass (so my pointy pink head thinks). Jam thingy. Technical jar lid thingy.
