... made a working model of a knee with two pvc pipes, rubber bands, bolts, screws and a piece of a bungy jumping rope, a ball, electric tape and a few zip ties.
We used some hot glue and some other little things to make it.
Now we are waiting for "our" results, to see if our project gets an A, if it doesn't I will be so depressed!
Hope you liked this little story, I went crazy trying to make it.
Thank you for reading.
