Astronauts on board the International Space Station have been trying out special cups to let them drink liquid.
In the past they've only been able to have a drink from pouches because there's no gravity.
The shape of the cup allows astronauts to flip, toast and even throw the cup without any of the liquid falling out.
It's wide at the back and then turns into a v-shape where you put it to your mouth.
This means that the liquid is guided carefully towards the users mouth.
Take a look at them trying it out.
