The manufacturer has provided the following approximate cubic feet of helium required per Cloudbuster balloon.

  • A 4 foot Cloudbuster requires 34 Cubic Feet
  • A 5.5 foot Cloudbuster requires 87 Cubic Feet
  • A 8 foot Cloudbuster requires 267 Cubic Feet

These are only estimates. The amount of helium should be around 10 percent plus or minus this amount.
