It maintains a constant pressure inside the frying chamber to avoid leaks, to prevent the oil from sloshing around and to use less energy to heat the oil. The experiment hardware is automated and closed for safety. Pop the bubbles using fewer shots to get a higher score. Match 3 or more bubbles to make them pop. Use the guiding line to aim your shooter and pop bubbles.

The experiment measured the temperature of the boiling oil as well as temperatures inside the potato – three levels deep. Whether you call it bubble shooter, bubble pop, bubble games, bubble empire champions, bubble witch saga, or panda pop - you can enjoy it all here. The experiment captured the frying process with a high-speed, high-resolution camera to capture the bubble dynamics such as growth rate, size and distribution, as well as the escape velocity from the potato, the bubbles’ speed and direction of travel in the oil.

The experiments were conducted on two ESA parabolic flight campaigns, whereby an aircraft flies in repeated arcs to recreate brief moments of weightlessness. To study how microgravity influences cooking techniques such as frying, a novel experimental carousel-type apparatus was designed to fly and be safe. High-speed video capture of steam bubbles in various levels of gravity from frying potatoes in oil – in an air-zero-g aircraft.
