Because birthday balloons are cheap and colorful, children like to buy them and play with them. Balloons were first used for scientific experiments and transportation, but they soon found their way into people’s hands as a tool for entertainment.
My oldest son is now 21 years old and still loves balloons very much. He plays with them like a child and it’s a lot of fun. Whenever I can, I buy him balloons all the time at https://balloons.online/licensed-mylar-and-foil-balloons/ . He likes balloons with different designs, so I buy him different ones all the time. He gets excited about them and it makes me feel good.
