What are 2 items that you couldn't use on the moon?

Question

List two items that you could not use on the moon. Why would they not work?

Answer 1

Regular Matches - No atmosphere to aid combustion (and any variation on an open flame really for the same reason).

A Can of Soda - Depending on what the local conditions are like, it will boil or freeze. And then you would have a hard time drinking it while wearing a space suit.



Basically, ANY item that is designed to be used by people on the surface of the earth would have a hard time functioning on the moon. Mostly because the environment isn't well suited for that item. For instance, nothing really prevents a standard flashlight from working on the moon. However, because of the temperatures, vacuum, regolith, etc. it's life would be severely impeded unless it had gone through a special design for its new environment. However, anything that requires an ambient atmosphere to operate would be in serious trouble... However, I can see getting around some of those limitations through clever design and engineering.

Answer 2

Do you mean: on the Moon's surface without any protection?



For example, a lighter (or a match) would not work: no oxygen.

A vacuum cleaner would not suck, because there is no air outside to rush inwards when the motor pumps out the air inside the machine.



However, if you can find a large enough cave, and fill it with air (and seal it from the outside vacuum) then a lighter will work.



However, a GPS receiver will not work. (the GPS satellites are around Earth, not around the Moon).



A cell phone will not work. Too far from the towers. At least, not without a special dish.



Most scales (especially the spring type) will be wrong (unless there is LOTS of latitude to reset the spring).

Then, it depends what you mean by "work". An electric fan would work in this way: if you can feed electical current to it, and turn it on, then the blade will turn around. However, it will not push any air around.



However, it you bring the fan inside the spacecraft (where there is air) and turn it on, it will work, even though the spacecraft is one the Moon. Therefore you could use a fan on the Moon (but not outside).

Answer 3

Hair spray - mist would fly everywhere, if the can didn't explode first.



Fishing Rod, Water Skis, Jet Ski, Hydrophone, Rain Coat, Umbrella - No water or rain on Moon.



- - - - -



Corvette Automobile - No gasoline on Moon; engine is air breathing, with no air on the Moon.



Cel Phone - No cellular towers on the surface of the Moon.



- - - - -



Piper Cub Airplane - No air on the surface of the Moon for wings to develop lift, or engine to breathe.



Assortment of vegetable seeds - No rain on the Moon which would be needed for seeds to germinate, and extreme low temperatures would prevent veggie growth. XRays and Gamma rays

would probably kill anything that was watered and warmed by human visitors.

Answer 4

A force scale because the gravity is not the same on the moon and a fan because there is no atmosphere on the moon.

Answer 5

A compass, no magnetic Field.



An airpalne, no air

Answer 6

a fan

a cell phone
