Recently in science, we have made our own “model arm” . We used everyday tools to create a wonderful project that can move just like a regular arm. We followed some easy instructions to make it, after that, we could move the arm like a regular one.

Here is little video of how to make it and what tools to use :

At the beginning, my hypothesis was that when I finished the arm, I thought I will mess up a few times but then It will work.

My conclusion was that it worked! I did not mess up and it worked!
