1. A balloon inflation system for simultaneously inflating a plurality of balloons, the system comprising:
- a plurality of assemblies each comprising a balloon and a tether connected thereto, the tether of each balloon being flexible and hollow so as to define an inflation conduit for delivery of inflation gas to the balloon, each balloon having a spout and each tether has(a) a first end inserted into the balloon at the spout of said balloon and the balloon is bonded at the spout to the tether in a manner to ensure that inflation gas can enter the balloon only via the tether, and(b) a second end remote from the balloon, the second end of the tether being connected in fluid communication with a manifold,the manifold being adapted to receive the inflation gas for delivery of said inflation gas to each of said tethers and the respective balloons, each tether being adapted to be severed so that the balloon and tether assembly can be removed from the manifold after the balloon is inflated, wherein each tether further comprises a one-way valve located at the first end of the tether and inside the balloon relative to the bond of the balloon and the spout to control the flow of gas through said tether, said one-way valve being adapted to prevent the inflation gas escaping from the balloon through the tether when gas pressure inside the balloon exceeds the gas pressure in the tether and wherein the balloon inflation system comprises a plurality of connectors each connected between adjacent tethers along at least a part of the lengths of said tethers to form a ribbon of tethers said connectors being severable so that the tethers can be separated from each other.

3. A method of providing a plurality of simultaneously inflated balloons, wherein each balloon is sealingly connected to a flexible tether at a spout of the balloon and each flexible tether also acts as an inflation conduit and is connected to a manifold, said method comprising the steps of
a) supplying an inflation gas into the manifold whereby the inflation gas is delivered through the respective inflation conduit to the respective balloon, and after each balloon has been inflated; - and
b) sealing each inflation conduit by utilising a duckbill valve for each inflation conduit, each duckbill valve located at an end of the tether within the balloon relative to the sealed connection at the spout of the balloon, wherein the sealing of each inflation conduit is in a manner to prevent deflation of the attached inflated balloon.
