does it come with a launcher?

It comes with part of a launcher. It has a base, a plug for the bottle, plastic tube, and adapters. You have to supply the bicycle pump. The pump connects to the end of the tube.

We are missing all of the instructions, what we need to know is were the 3 small connectors go.

I'm so enthusiastic about this thing, I've taken a photo of the instructions and posted them here: http://whereisbarney.com/erase_after_2030_01_01/4M_Water_Rocket_Instructions/

How long does it take to dry?

Several hours to overnight depending on humidity levels.

The description says pump included yet all the reviews reference their own bike pumps. Which is it?

This does not come with a pump, but you can use most pumps, even ball or toy pumps. We used a Spalding 12" Dual Action Pump which I normally keep around for pumping up basketballs... it's only about $7 on Amazon and is way more portable / easy to stick into a backpack with the rest of the rocket kit (and a gallon milk bottle full of water for fuel). A good 4-6 pumps with the Spalding will launch the rocket even when the stopper is on pretty tight. One of the three little plastic plugs that connects to the hose is threaded and will screw right into the Spalding pump's top, the same part that a pump needle would normally screw into... so if you have a pump that can take a screw-in needle adapter, it should fit with one of the three plastic adapters included in the kit.

Impressionnant

Honnêtement je ne pensais pas trouver un article de cette qualité, mais cette fusée monte vraiment très haut ! 40-50 m de hauteur facilement. Très impressionnant pour mes enfants. J'en ai achetée une deuxième pour mon neveu.
