We printed and inflated 4000 balloons for the annual festival in London Chinatown. We arrived early and setup a workstation including pre-cut ribbon, helium cylinders and inflating equipment.
5 Experienced balloon crew were required to keep pace with demand as we were hand tying, no plastic valves were used.  We managed to build a stock up in the morning but at lunch time me were hammered by the crowd, we could hardly keep up, as quick as we inflated they were given away.
The event also included street entertainers and oriental food tasting and as a bonus the weather was perfect. The PR Agency we were working for employed promotional crew to give the balloons away so we only had to concentrate on inflating as fast as we possibly could.

We were back again in 2015, but this time it was 4500 Red balloons:
