B. law of conservation of mass
This is why the total amount of and element before and after a chemical reaction is constant.
when John Travoltage rubbed his foot against the floor, he started building up negative energy, this negative energy later built up as he was rubbing his foot on the floor which then caused a reaction with the door knob, the same thing happened with the balloons, as we rubbed it on the sweater, the balloons started building up negative energy too, which then resulted in a connection with the positive energy. The dust particles most likely got a charge from moving around from different places, considering that fabrics build up the negative energy, it appears that the dust particles could have landed on a fabric which then allowed the particles to build it up and then stick to other surfaces.
Temperature and pH levels are both correct
