Awesome idea:birthday party decor,take diffrent color table cloths and tape them to to ceiling like that. Then tie 3 diffrent color balloons together and tape them to another set of balloons then tape the all the balloons in the middle of the table cloth.
No helium needed to fill balloons for parties.just vinegar and baking soda! I NEED TO REMEMBER THIS! this is important since helium is not a renewable source and is in such short supply-kid science project
