    13. How long is a balloon prior to inflation? How long is the balloon inflated? Letting the balloon deflate, how long is the balloon now?

Balloon Sizes
Balloons come in different sizes and are denoted by a manufactures numbering system.  The first number represents the diameter in inches and the second number refers to its length. Typically, balloon entertainers use the 260 twisting balloon.  These balloons are 2-inches in diameter and 60-inches long.  While other balloon sizes like 160, 321, 350, 360 and 646’s are used for detail or making very large balloon animals.

Caution: Balloons are fun toys, but can be dangerous like all toys...PLEASE make sure small children do not chew balloons or have access to broken bits. We would like all our kids to grow healthy and happy. I ask you to be responsible like professional balloonist. Adult supervision is recommended.

Twisting Tip:

When a balloon is uninflected their colors can be deceiving. Dark purple, green and brown balloons can look like black balloons.

To help distinguish the different colors, stretch the balloon nozzle over your finger in bright light or fluorescent lighting. This will show you the true color of the balloon.
