UAE astronaut Sultan Al Neyadi has asked people to explain a rare physics event that took place on the International Space Station.
He was seen spinning an iPad three times but on the last spin the device rotated in different directions as opposed to the constant movement on the first two occasions.
Dr Al Neyadi, 41, demonstrated the intermediate axis theorem in space, also known as the Dzhanibekov effect or the Tennis Racket Theorem, which was discovered by Soviet cosmonaut Vladimir Dzhanibekov on the MIR space station in 1985.
"This question is for the smart ones," he said in a video posted on his Twitter on Monday. "An object's movement is as shown in these three cases.
"Have you noticed that in the third case, the direction of movement kept on changing unlike the first two cases where the direction remained the same. Can you tell me why?"
The theory states that objects, except for ones that are circular and square, have two axes and when that object rotates, it spins in a stable condition.
But when the rotation happens around the intermediate axis, it is unstable, causing it to spin in a different direction than expected.
And when this is done in microgravity, the physics phenomenon is even more fascinating.
Dr Al Neyadi arrived on the ISS on March 3 for a six-month stay and has already begun some of the 219 science experiments assigned to him by Nasa and UAE universities.
He harvested tomatoes that were planted by a Nasa astronaut in December, as part of a botany investigation and also for crew consumption.
Fresh supplies are being sent on Wednesday on a SpaceX cargo resupply mission, which will deliver experiments, food and other items to the new astronauts on board.
There were 11 people on the ISS, but four departed this weekend and landed safely back on Earth.
Crew members include station commander Sergey Prokopyev, flight engineer Dmitri Petelin, both from Roscosmos, and Nasa flight engineer Frank Rubio.
They were supposed to return to Earth last month but the Soyuz spacecraft on which they had arrived suffered severe damage from a micrometeorite.
A replacement Soyuz was sent and will bring the astronauts back home in September.
This means the crew will complete a year in space and replacements will be sent as they return.
On May 12, four private astronauts, including two from Saudi Arabia, will travel to the ISS for a 10-day stay.
The Axiom-2 mission will lift off on a SpaceX Falcon 9 rocket from the Kennedy Space Centre in Florida.
The Saudi astronauts are Ali Al Qarni and Rayyanah Barnawi, who is set to become the first Arab woman in space.
This will bring the number of Arabs in space together simultaneously to a record of three.

WHAT IS A BLACK HOLE?
1. Black holes are objects whose gravity is so strong not even light can escape their pull
2. They can be created when massive stars collapse under their own weight
3. Large black holes can also be formed when smaller ones collide and merge
4. The biggest black holes lurk at the centre of many galaxies, including our own
5. Astronomers believe that when the universe was very young, black holes affected how galaxies formed

TERMINAL HIGH ALTITUDE AREA DEFENCE (THAAD)
What is THAAD?
It is considered to be the US's most superior missile defence system.
Production:
It was created in 2008.
Speed:
THAAD missiles can travel at over Mach 8, so fast that it is hypersonic.
Abilities:
THAAD is designed to take out ballistic missiles as they are on their downward trajectory towards their target, otherwise known as the "terminal phase".
Purpose:
To protect high-value strategic sites, such as airfields or population centres.
Range:
THAAD can target projectiles inside and outside the Earth's atmosphere, at an altitude of 150 kilometres above the Earth's surface.
Creators:
Lockheed Martin was originally granted the contract to develop the system in 1992. Defence company Raytheon sub-contracts to develop other major parts of the system, such as ground-based radar.
UAE and THAAD:
In 2011, the UAE became the first country outside of the US to buy two THAAD missile defence systems. It then stationed them in 2016, becoming the first Gulf country to do so.

Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.
