Science journal week 3

On the third week we did the balloon experiment again but this time we had fish wire. We used the fish wire to change the amount of friction acting on the balloon. We had the wire going from the monkey bars to the rope climbing wall, we had the balloon going up to see if it changed the speed but for some strange reason the balloon kept looping around the wire. I think that was because the wire was loose but no matter how much I tightened it still spun maybe it was to steep. That is probably the most because with the acting air plus the force and air resistance on the balloon would make it spin. likely the angle or gradient would change the experiment most likely the amount of force acting for it to go up.I think I am relasonal on the rubric because I thought of what could be making the balloon loop and slowing it down.
