Water bottle rocket method

Hello everyone, Last week we were started to make a bottle rockets we launched on the same day we made them here is what we did.

Materials

Water bottle paper tape water rocket launcherAir pump

Step 1. I will use paper to make a cone shape and cellotape it to the bottom  of your bottle

Step 2. Fins I will cut paper into triangular shapes and then use cellotape to the fins you wnat to cut out 4 fins out then stick them on the bottle.

Step 3. launch time half fill the water bottle with water. Place the bottle on the rocket launcher. Pump the air untill it launches.

You will need to put the bottle on the rocket and get ready for what is about to happen.

How well my bottle rocket flew

It went pretty good we had lots of thurst to it the air friction was kind of good. the gravity/weight it went down really fast because of how much gravity it had to it and the wind it was a bit windy when we did it  but all of us had fun doing it.
