Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: The Materials
OK these materials are redially available to me because I rock climb but most other materials are redially available at home depot and REI (I am in the USA so it might be different for you if you live elsewhere)that being said I AM NOT RESPONSIBLE IF YOU HURT YOURSELF ADULT SUPERVISION IS REQUIRED AND BY ADULT I MEAN RESPONSIBLE ADULT ALSO PLEASE JUST USE COMMON SENSE so with that all out of the way here is what you need...
1. rock climbing harness
2. 2 100 foot lengths of rock climbing rope or steel cable
3. 1 come along AKA hand winch
4. a couple caribeners (3-4 max)
5. a ladder
6. a large pulley
Step 2: Locate Your Trees
now if you have a large backyard with many trees as i do this is a relatively easy task but below is the tree formation you are looking for basically a tree formation in a "T" completely onobstructed by bushes and other trees (also i apologize for the horrible bitmap image i am not too good at digital drawing)once you have located your trees move on to the next step.
Step 3: Setting Up Rope 1
this is where your responsible adult comes in now depending on the height of your zip-line set the ladder up on the base tree climb the ladder and firmly secure the rope to the tree with good knots then walk the rope to where it is in-between the other 2 trees
Step 4: The Yoke (that's What I Call It)
the yoke consists of a length of climbing rope stretched between your 2 trees the yoke rope is suspended off the ground and is connected to your main rope (the one coming from the base tree) using a caribeaner the base rope AKA the main rope is actually suspended in the air by the yoke so to build the yoke string the rope and pull it TIGHT with the come-along but be mindful to thread the main rope with the pulley before pulling the yoke tight
Step 5: Now Ride That Thing!
provided you have done all steps correctly you should be in business all you need to do is put on your harness climb the ladder on the base tree clip in to the pulley and go down as for getting off the zip-line have a responsible person bring you a ladder to step on while you get off now with that all being said have fun be safe and don't let your friends strand you by not bringing you a ladder
