Nathan's chapter challenge 2020 Flying fox

For chapter challenge, I did a zipline I think it is a supernova I put in a lot of work and took a video the hardest part was building it the best part was attaching it to the string and making it go down this activity was fun at first, I had a little string but it was not long enough so the next day I tried it again from a higher place and it worked way better and underneath were the people are standing there's some stuff like food and then the Yellow on the top is a little fence so you don't fall off and the top part that attaches to the string for that part I yous the inside of a tire a gray thing that makes it spin but you need a gray one, not a black or a blue one because the gray won is the only one that spins and then I got a long piece with wholes in it so it could be attached to it and at the bottom is a block that makes it hold on the bottom and the roof is very strong and its the same pecae for the botem of it and this didint take me a long time to buld it.
