Imagine during your cruise vacation you stopped on a deserted island to take in all of nature’s beauty. While you were enthralled by the untouched island, the cruise ship leaves! Now, you are only left with your cell phone and some random materials. Your cell phone doesn’t work at all on this island, but you know from a previous stop there is another deserted island where there is plenty of service. It is a short distance away and an easy swim, but how will you get there without damaging your cellphone? Your challenge is to build a contraption that will be able to float behind you while you swim to the other island.
Your cell phone raft does have some criteria and constraints. The raft has to be tied to your body so make sure to include it into your design. You can’t hold the contraption or the phone above your head since you need that arm to swim! Your phone needs to stay completely dry for fear of not working at all. Only the materials provided can be used in your design. While testing out the device, it can be pulled by the string from one end of the water to the other at a moderate pace.
