Edward Said:

If i were on the moon what materials would i need?

We Answered:

If your on the moon, you will need some sort of environment to protect you from the lack of air on it (also known as a vacuum). Nowhere on your list do you include a spacesuit or some sort of shelter that you can live in.

Your dead.

Powering a fountain/filter for a container water garden?

We Answered:

from my experience one has to have a pump going 24/7. this keeps the water flowing and if the pump has a built in filter it also keeps the water clean. occasionally you may have to change the water as depending on how much sun your container pond gets it will have some degree of green water which is algae. the snails help to keep the algae that grows on the bottom and sides of your container cleaner,but a good filter is a definite plus. check with your local Earl May or where ever you are getting the container pond from. Sometimes less is better when it comes to small container ponds as you are wanting to do.

Crashed on the Moon, prioritize these 15 items?

We Answered:

1. Two 50kg oxygen tanks

Single most useful thing you can have. The good news is gravity is low so you'll actually be able to carry them.

2. Parachute silk

Portable shade.

3. Solar powered FM Reciever, transmitter

You might hear something useful and you can let your destination know you're coming.

4. Nylon Rope, 50m

While not terribly useful, it will help in getting your friend out of that crater.

The rest is really, really useless and should be left at the crash site.

Matches - No firewood, no air in space.

Food Concentrate - You'd have to take off your helmet to eat.

Portable heater unit - The moon lacks wall sockets.

Two .45 caliber pistols - Sadly you won't even be able to commit suicide with these. They'll vacuum weld and the explosives won't go off without oxygen.

Dehydrated milk, one case - More food you can't eat.

Star map, moon constellations - Navigating by the stars is a good way to get lost.

Compressed CO2 - Unless you have some kind of jump jet this has no obvious purpose.

Magnetic Compass - The moon has no magnetic field. This is a paperweight.

20 litres of water - Wow, this would be nice if you could take off your helmet and if it was below the boiling point.

Signal flares - Stuff doesn't burn on the moon.

First Aid Kits, Injection Needles - Because you're going to inject your partner through his spacesuit? Or are you supposed to McGyver something involving the water or the CO2?

EDIT: Hmm, you learn something new every day. The flares would burn as would the gunpowder.

I still suspect the gun will vacuum weld.
