There are primarily two types of balloons based on the material they are made from: latex balloons, made from natural rubber, and foil balloons, made from metalized nylon. Latex balloons are affordable and biodegradable, while foil balloons are more durable and can hold helium for a longer period of time.
* While it would be nice to have a date no, you don't need a girlfriend to go to a prom. Many teens go as a group and some have girlfriends and others don't. You can also bring a best female friend with you or just go in a group.
There are a variety of balloons available, including latex balloons, foil (mylar) balloons, helium balloons, air-filled balloons, water balloons, and LED light-up balloons. Each type serves different purposes, from decorations to entertainment.
A teen will need a formal dress for prom. Prom is a very formal affair for high school students that allows them the chance to dress up more formally than usual.
