# Fluid Pressure: Drinking on the Moon

CLMECH-G2HTST

The Moon has gravity about $1/6^{th}$ as strong as Earth's, but no atmosphere. Suppose an astronaut on the Moon had a special fixture in his helmet that would allow him to insert a straw through his helmet face-plate in order to safely drink a soda (the cup of soda remaining outside).

Assuming the liquid in the soda did not boil away or freeze, would the astronaut be able to drink his soda?

A

Yes, it would be just like drinking through a straw on Earth

B

Yes, it would actually be easier than drinking through a straw on Earth

C

Yes, but it would be more difficult than drinking through a straw on Earth

D

No, because the lack of air pressure would make it impossible

E

No, because the lower gravity would make it impossible
