Buoyancy Units are used to measure buoyancy.

One BU is able to lift 0.845 units of mass (found experimentally).

Achieving weightlessnessEdit

In order to find the needed buoyancy a given formula is used:

B = 1.183 * M where:

  • B is the needed buoyancy.
  • M is the total mass of the machine.

A common mistake is not taking into account the mass of the balloons thus creating many misconceptions.

In order to find the needed buoyancy for a given raw mass this formula is used:

B = 1.183 * (R + 0.217 * N) where

  • B is the needed buoyancy.
  • R is the raw mass of the machine.
  • N is the number of balloons used.

1.183 is a constant for converting buoyancy into mass. 0.217 is the mass of a balloon. Both are found experimentally. Currently no correlations to mathematical and physical constants (eg. pi, e, g, etc.) are found yet.
