These balloons
come in a variety of sizes and shapes. A number of the balloons
are based around cartoon characters from films or TV programmes.
They make
great gifts for children and adults.
The size of
each balloon is shown beneath the relevant image of the balloon.
With this
type of balloon it is difficult to give a precise floating time
because this is is dependent upon the shape and size of the balloon.
Generally the bigger the balloon the longer the floating time.
They will
float longer than the 18" balloons, normally between 18-30
days. After a few days the balloon will start to show signs of
deflation, but will still float. The exact floating time depends
on a number of environmental factors mainly air temperature. The
warmer the air temperature, the greater the loss of helium, thus
the balloon does not float for so long.
The balloon
is made of a metallic foil, often known as Mylar and is filled
with Helium gas which makes it float.
