00:52 is the only real clip that really shows anything. In the other clips the rubberballon scatters all around the room so naturally there will be a loss of mass on the bursted side. consider doing the experiment with a basket around the ballons.
This is an excellent demo and one i cant believe i never thought of before. If you weigh an empty balloon and blow it up and weigh it again the difference is so slight that often it doesnt show any difference(depending on the electronic balance). Students then remain unconvinced. I will definitely do it this way the next time. Thanks
