Challenges faced: if the serenges were filled all the was up to the top then the lift wouldn't move to its full potential and it wouldn't move properly if it had to much air either. Making sure the tube didn't make the structure off balance and fall. Make sure that the serenges got the water flow proper. Making sure that the serenges in the middle of the hand was placed properly so the hand can move up and down to its full potential.
