How much support will I need to make a rainbow arch w/linkaloons for a float?

We are making a float for a parade this Thursday 7/24/08. We have a tank of helium, 300 linkaloons and a 10 x 12 trailer. We wanted to have 4 or 5 rows together to look like a rainbow, but I can't figure out what kind of support I need to keep them from blowing too much. Any ideas?

Hi Cheryl,

For outdoor conditions, the best thing you could do is build an air-filled arch on a solid frame. Otherwise it will sway in the wind. The design you have in mind has two major problems: first, helium balloons expand much more in hot conditions than air filled balloons do, so there is a bigger risk that some of them are going to pop. Secondly, with link-a-loons, you won't have a solid frame.

The only support I could suggest is to use strong fishing line together with the link-a-loons (as you would with a normal string of pearls arch) and then secure the fishing line with tethers to some anchor points on the float.

Wishing you good luck and I would love to see a photo of the float!
