MagicArch
MagicArch modules make striking balloon decor that assembles in a fraction of the time it takes for traditional arches and columns...and lasts twice as long! MagicArch modules use a unique, cloverleaf design with a single valve. In effect, this allows you to inflate four balloons at once to an exact uniform size. Just fill them, string them together, and there you have it - a perfect finished arch!
To calculate your MagicArch, you would add the width plus the height of the space in which you want the arch to fill, and multiply that sum by 2. This will give you the number of balloon modules you will need to complete your arch.
Length + Width x 2 = Number of Modules Needed
*If filling your arch with helium, you may use monofiliment line, string, or curling ribbon to string the modules.
*If filling your arch with air (which will allow the arch to remain for up to several months), you may use conduit or pvc pipe.
