Welcome to your Survivor immunity challenge! You are to break up into randomly chosen teams of two. Each team will get a length of rope, a protractor, and a 1 ft ruler.

Your teams need food to survive on the island, and the only food is hanging from a coconut tree some distance away. You are seperated from the tree by a flowing river filled with viscous and hungry pirhana, and if you attempt to swim across the river, you shall surely perish. You may be able to build a rope bridge over the river by throwing a rope across to the coconut tree, but you need to know how far away the tree is in order to determine if you have enough rope.

The first team to accurately determine how far away the tree is will win the immunity challenge (in this case, you get first pick of the end-of-week projects).

After the first team to finish submits their solution, the other teams must submit an answer within five minutes, or forfeit their chance at the immunity challenge. The closest of the values submitted will win.

This means both accuracy and speed will be vital for you to be...

a Survivor!
