4ft Virgin Media balloons helium filled to promote cloud computing. It’s tricky to price a job that involves large balloons as it’s difficult to calculate the amount of helium required. I looked at the cubic capacity of a 4ft balloon and compared this with the BOC helium chart – so I calculated an L size should inflate 9 x 4ft balloons……. Then I added 50% extra helium for luck.
The client required the 4ft balloons to support fake computers. I’d given the lift capacity of a 4ft and these fake computers were made to a certain weight. We inflated a balloon to 4ft and attached it to one of the computers…… It didn’t lift it!
Lucky these 4ft balloons seemed to be more like 6ft, so we untied it and inflated it to 5ft (good job I had applied my 50% extra rule). The balloon lifted the computer and still had plenty of give for more gas if required.
We also completed a ceiling fill. There were 2 rooms involved and we decorated the 2nd room with 16″ balloons attached to 500lb line (these IT guys don’t like ribbon). We had a 3 hour window to complete this between 6am to 9am, we finished at 8.10am. The location was awesome, next to Clarence House.
