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
Neat idea for a kid's birthday party, tie balloons to favor bags. They will be festive party decor, plus every kid wants to take home a balloon! maybe that way I don't forget to give the favors tobtge kids!
