How To Make a Simple no pump water rocket

Intro : simple no pump water rocket

this is a fairly simple water rocket using only the pressure from your tap ,suprisingly there is alot of force from the tap and this rocket will put it to use in a simple way ,at a low cost  . it can reach heights of 10m-20m    30ft-60ft

 

 

First Step : materials

you will need:
pvc cement
a male director that screws into a gardina nozzle width 25mm( 1 inch).
about 4cm (2inches) of 15mm pipe (0.6 inches)
a male director that screws into a gardina nozzle width 25mm(1 inch)
Gardina nozzle
cable ties

tools :
hands

 

 

 

 

Step 2 :

screw the male director into the gardina nozzle
(tightly)

Step 3 :

just push the pipe onto the male director (it should be tight)

 

 

 

 

 

 

Step 4 :

get your threaded pipe and screw it into the  plug that fits into the bottle , length dosent matter that much
2 examples shown

Step 5 :

now brush on the cement on the inside of the threaded pipe and the out side of the 15mm pipe

 

 

 

 

 

 

Step 6 : your done

now just let the cement dry, mount it onto a post , fit a bottle and hit the water

 

 

 

 

 

 

 

Last Step : for extra height

the pressure can be improved by covering half of the plug that fits in to the bottle with electrical tape or another thin tape that stretches
