Children's party decor can't be just for watching, especially if it's made out of balloons. Who can refrain from touching a balloon? I had never seen such a person. Balloons call the handles to themselves, so let them be fun too! You can entertain your guests with a variety of balloon figurines, which will make the party a unique and unforgettable event in their memories. Children under 8 should not play balloons without adult supervision!
Do not forget that the balloons are there because of this event, and there is no need them to "survive" longer than that event, so let the guests freely destroy them. However, these are just decorations, and the most important thing is having fun and having fun, and you should not regret your investment if it really fulfilled the purpose. Just remember to throw away the parts of the destroyed balloons right away so that smaller children do not put them in their mouths!
