The Reference mUltiscale Boiling Investigation experiment, known affectionately as Rubi, aims to expand our knowledge of the boiling process.

Understanding how boiling behaves in weightlessness is imperative because gravity plays an important role in this process.

Without gravity, boiling takes place in slow motion and produces larger bubbles. This will allow scientists to observe and measure effects that are too fast and too small on Earth. With this insight and more accurate calculations of the boiling process, products such as laptops can be improved and made more compact.
