I thought i made the strongest loop ever but i actually didn't follow instructions! I used metal strings to fortified the loop. I tightened the strings to the max and when i knew that i was against the rules , i tried cutting them with big big cutters , i manage to cut them but ended up with bristles in my hand! I even saw the bamboo poles to fit the loop nicely inside.
My fault for skipping instructions! :(
Lesson learnt : clever good enough , don't act smart!

Haha thats all , i need to think of ways to redo the loop.
