Toe poppers are a hollow stick with a shotgun shell in one end placed over a board with a nail in it. When one steps down on the Pipe shoving it down on the Nail the shell fires. Hence why they are called Toe Poppers...
Thanks for the Rep! Not only would I have a Pongee Pit but I would also have 12 gauge toe poppers on the lips of it for those who might want to jump across it...
