*Colored ice balls* Fill balloons with water and add food coloring- red and green would be great around christmas! (be careful not to let the food coloring escape!), once frozen cut the balloons off and voila! Look like giant marbles :)
I wish I knew this tip for filling balloons with treats! 44 for Halloween sucked! to fill balloons. Instead of pinatas for parties. Great idea so that each child can pop one balloon and get the goodies inside.
