Results Part 1

Blow the foam tablets softy. When they swaying but they stick together. When blow heavier, it swaying again then move around in the button. And blow it is the heaviest the foam tablets will spread out quickly around the plastic bottle.

Results Part 2

When put Potassium permanganate crystals into the water it turn to be violet. And smell it quickly.
