How to launch a water rocket

Equipment

• 2l  plastic bottle  
• Air pump
• Water
• Aqualad rocket
• String for pressure launcher 
• U peg for stand 
• Safety glasses 
• Open field 
• 10 pumps of air 

Method 

1. Fill the bottle with water a quarter of the bottle.
2. Then in then look for an open field then put all the stuff like safely glasses on
3. then bring air pump and the string 
4. Grab the bottle then flip the stand upside down then screw it on.
5. But put the peg under it  so the launcher doesn’t fly away .
6. Next grab the string then put your safety glasses on.
7. Then step on the pump 10 times then grab the string 
9. Lastly pull it then it will fly.

Rocket tips

We did 20 to 40 but we did not do up to 50psi. That was our limit.

If you do it, wearing safety glasses comes first.  

We have been learning about forming hypotheses to predict the results of experiments. we used water rockets to experiment and checket our results. I liked when we launched them it was fun to watch

We have  been leaning about forming hypotheses to predict the results of experiment we used water rock to experiment and checked our results.

I liked the line that you can step on the equipment.

Equipment

• Water
• Air pump
• A peg for stand
• Safety glasses
• Open field
• Aquapod rocket launcher
• String for pressure
• 2L Plastic bottle

Method

1. Put on the safety glasses.
2. Fill the bottle with water and put the bottle on the aquapod.
3. Put the peg so you can get up.
4. Get and step on the air pump and on the aquapod rocket hole.
5. Now you have the string tied to the aquapod.
6.  but if you don’t, you have to get your aquapod and the. string and tie the string on to the aquapod.
7. Now you have to pull the string.
8. And you see it’s launch.

tips put less water and it will go faster or you can do no water or a lot of water and it goes slow

We have been learning  about forming hypotheses to predict the results of experiments.

we used water rockets to experiment and checked our results.  here is my work.

  Instructions

• 2L plastic bottle 
• Air pump
• Water
• Aquapod rocket launcher
• String for pressure release 
• U peg for stand 
• Safety glasses
• Open field

                                                Method

1.  Must fill the plastic bottle ⅓ full with water.
2. Put your safety goggles on for the full experiment.
3. Be ready because you might get wet.
4. Press the air pump to whatever amount you want.
5. Make sure there is no one near you so they don’t get hurt.
6. Press the air pump to whatever amount you want.
7. And pull the string to have the fun that you have been waiting for!

                              three  pro tips needed to help

                       Make sure you check the water level

water provides the mass (thrust)

too much water makes the rocket too heavy and it wont fly

I hope you like it.

My favourite part was when we launched the rockets pressure to 39 PSI and launched it.

Equipment

• 2L plastic bottle
• Air pump
• Aquapod rocket launcher
• String for pressure release
• Peg for stand
• Safety glasses
• Open fieldMethod
  1.  first fill the plastic bottle ⅓ full with water
  2. put on your safety glasses than get the air pump 
  3. And get the peg and get the rocket launcher than get a string 
  4. Go to an open field then sit up the equipment then put the water bottle in the rocket launcher 
  5. Put the peg up then push the  air pump down how many times you want but if you want it to go high push the air pump about 15 times.
  6. Launch it by pulling the string.                                                                                                                                                                                                                                                                                                                                                    

We have been learning about forming hypotheses to predict the results of experiments. We used water rockets to experiment and checked our results.

We went outside and put a plastic bottle filled with a third of water then you put it on the launcher and pump air into it with an air pump then you pull a string and the bottle goes flying up and across the way that the wind is going.

Then we went inside and did instructional writing about how to launch it.

Here is my instructional writing.

How to launch a water rocket 

Equipment 

• 2L plastic bottle
• Air pump
• Water
• Aquapod rocket launcher
• String for pressure release 
• U peg for stand
• Safety glasses 

Open field

Method

1. First put a pair of safety goggles on so that you are not sprayed in the eye. Place the Aquapod rocket launcher in an open space with no trees around a field or a  park is a good place for this.
2. Next fill your 2L plastic bottle up with water until it is ⅓ full, then put it in the bottle launcher by attaching the bit where you drink from onto the bottle stand.
3. Next place the U peg over the Aquapod rocket launcher and push down with your foot so the peg goes into the ground until it is sturdy enough that it would not go flying.
4. Then plug the air pump into the aquapod rocket launcher piece so that when you press down on the pedal air goes in.
5. Push down the pump until the PSI gets to about 35 then tie the string around the fake cap on the aquapod rocket launcher so that when you pull the string it turns the safety lock and the  bottle goes flying.
6. Well done you have successfully launched your rocket

Mounts and thrust

If you put a lot of water in a bottle rocket and then put the air in it, it will not go as high as a third of the bottle rocket filled with water.

But if you put no water in the bottle rocket it will just do flips in the air  and would not go far.

If it was 75% then it would do the same thing as if it was full because there is still too much water in the bottle rocket.
