Chocolate, movies, and books are things that astronauts pack to make life on the shuttle more like home.

00:00:10,000 --> 00:00:14,000
But perfume, video games, and even teddy bears aren't allowed.

00:00:14,000 --> 00:00:18,000
These items create off-gassing or give off atoms of gas easily.

5
00:00:18,000 --> 00:00:22,000
Gases, whether you smell them or not, can cause problems in space.

00:00:22,000 --> 00:00:24,000
What else do astronauts pack for the trip?
