I love relaxing with a cup of tea. Unsurprisingly it's a bit of a challenge for astronauts to do the same.
Without gravity pulling things down, aboard spacecraft liquids move around in unexpected ways. Escaping liquids can be hazardous, so astronauts have always drunk from bags to stop spillages.
Thankfully scientists have finally designed a weirdly shaped cup that can be used in space. It uses surface tension to keep liquid in it whatever angle it's held at. Astronauts can even do flips without spilling anything.
