Half fill the bowl with warm water.
The paint will be very difficult to remove, so don't use your favourite bowl. Wearing the rubber gloves, take the paints, shake them well and drizzle a teaspoon of whichever colours you want into the bowl of water. Silver and red go well together, as do blue and green, but the choice is yours. The more colours you use, the greater the kaleidoscope effect you will create. If the colours move to the side of the bowl, give it a quick stir so that the paint is swirling around the bowl.
