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!

Does salt make ice melt faster or slower?
Salt will always melt ice quicker than both of them. This is because in the same amount or volume, there are more molecules of salt than sugar or baking soda due to the chemical make-up. Salt, baking soda, and sugar will all act to lower the freezing point of the ice, making it melt quicker than the untouched ice cube.
