Question:
What material makes the food coloring move when you put a swab with liquid soap?
Hypotesis 1:
If we put some milk in a dinner plate, pour some food coloring and put a swab with
liquid soap, then the food coloring in the milk would expand and start moving to all directions because the soap makes a big chemical reaction with the milk which makes the particles of the milk go crazy.
Hypotesis 2:
If we put some water in a dinner plate, pour some food coloring and put a swab with
liquid soap, then the food coloring in the water would expand and make a circle because the soap in the water make only very few reaction and only cause the food coloring to make a cicle.
