Samantha got to the shore and ran for the cover of the jungle. She ignored the other women there and worried about her own good. She ran until she was out of breath, then fell into the ground, panting heavily. She took off her shoes and took out the knife.<em>"I have to become invisible,"</em>she though to herself,<em>"I can't do that with a tracking device, who knows what they plan on using them for."</em>She took the knife to her shoes and started cutting rubber strips from the soles.<br/><br/><em>"They didn't seem to concerned about my knife,"</em>she thought,<em>"I guess they don't realize how much it helps in survival. For starters, it's a cutting tool, that can be used to hunt, carve other weapons, and make all kinds of things. Secondly, and the thing many people don't think of, it's a mirror."</em>She used the knife as a mirror to examine her collar. She took the rubber strips, and carefully used the knife to create a small space to slide the rubber between the collar and her neck. She didn't need to worry about any metal contacts, because the water would have set them off as well.<br/><br/>She lined her neck with the rubber strips, then looked at the collar for another few minutes, turning it every way she could to try and figure out the best way to disarm it. Finally she wrapped one hand in rubber, and used the knife in her other hand to pry open the grooved pieces. It took about ten tries before she got the knife to slide into the mechanism.<em>"Yes,"</em>she thought as she smiled.
