Prepare two 1250 ml PET bottles2
Cut one of the bottles into three parts. Please keep the bottles top and middle section.3
Stick the bottles top into the other PET bottle's bottom part. 4
Stick the first bottle's middle section into the second bottle's top part. (Please use the insulating tape.) 5
Cut four acrylic boards as the four empennages of the rocket. 6
Pour about 200 ml Water into the bottle. 7
Cap the rocket into the inflater ready to launch. 8
Put the rocket into the launch pad. 9
Pump the air into the bottle. 10
Make sure the atmospheric pressure in the bottle is about 70~75 percent. 11
Launch!
with compressed water
There are two forces acting on a water rocket. The thrust which the force that is given to the water rocket to make it move, and the other one is the gravity.
You can make a stand, this will stable the rocket and allow it to stand up-right.
you put some water in the bottom of your rocket/bottle and get a bicycle pump keep pumping air in to the rocket sets off and make sure you watch your face they can be highly dangerous! hope this helps
to make it stand up
Unless you cook with Hydrogen and Other Highly unstable chemicals then you can only make a water rocket
by water being placed into the bottle and then, when you launch your rocket, the rocket will spin (if it has at least 2 fins) and the water will spurt out and make the rocket go higher in the air. (Tip:the more it spins,the higher it will fly)
