When you set your Booby Trap you are going to want to stop it moving about and remove the possibility of being pulled over by the Trip Wire.



To give you the ability to fixed down make 4 holes. Two on one side of the Bottle Top and two on the other. Then thread some string through the holes and tie a knot.



All you need do now in order to fix your Booby Trap in place is to either Sticky Tape the string down, or use the two Drawing Pins like in the picture below.



This also gives it the ability to be fixed vertically to a door frame etc.
