Why does dish soap repel glitter?

Soaps and cleaners are designed to break down the surface tension of water. When you added the dish soap or toothpaste to the water it broke up the surface tension. The water molecules, however, want to stick together and maintain that tension, so they move away from the soap, carrying the glitter and spices with them!
