Blow up a balloon and stabilize by taping the tied side of the balloon inside a styrofoam cup. Brush top with a thin layer of podge. Place the coloured mosaic squares all over the coated area. Repeat podge and square process 4 times, allowing time to dry between layers and ending with a layer of podge. Once completely dry, pop the balloon and add another coat of podge to the inside of the bowl, let it dry and you will have a beautiful, colourful bowl! Also try this project with glitter or sand!
