hi i want to make a fire truck but first i want to now how i pomp water like this because i dont no it

[efferman]

you need a bottle, two hoses and a compressor.

both hoses goes through the cap.fill the bottle with water, one of the hoses ends at the bottom of the bottle, the other one, which comes from the compressor, ends directly under the cap. , start the compressor and you should make your environment wet.

You make it a little hard for us to answer you by writing like this. Proper English would let us avoid many misunderstandings.

of a Lego Water Pump that illustrates what efferman was saying. robbiemccarthy's description of the video reads:

"Using a basic principle of concentration gradients, I built this water pump out of nothing but Legos and a plastic water bottle.

More information here: http://web.me.com/robbiemccarthy/Compositions/pump.html

How it works:

One Lego motor, drawing power from a Lego battery box, activates a Lego pneumatic pump which pumps air through one tube into the sealed water bottle. The water is forced out by the increasing pressure into the other tube protruding from the cap; into a plant, cup, or any other vessel in need of a soaking.

One variation of this which i have been wanting to try, is connecting it to an RCX or NXT brick. By doing this, I could make it light sensor activated, so it waters my plant ever morning. (As long as the RCX/NXT has an external power source, which you can find online.)"
