Any bottle than can fit a cork in the neck of the bottle will work, just make sure it is an airtight fit.

How high does it go?

Community Answer

If the rocket is built correctly, it could go a couple dozen feet in the air!

Question

Can I use superglue instead of a glue gun?

Community Answer

No. Superglue does not work the same way that glue from a glue gun does.

Question

Is it possible to make a water rocket without a cork?

Community Answer

No, because in order for the rocket to fly, it has to have air pressure built up inside. The cork in the neck of the bottle allows the pressure to build up.

Question

What can I do if I can't get all the things I need to make my water rocket?

Community Answer

Improvise! Maybe you can find some junk in your home you can use. You could also set this project aside for next weekend and ask your parents to help you get the necessary items.

Question

What will happen if I don't have a bike pump?

Community Answer

If there was no bike pump, then it could be more difficult to build up pressure in the rocket.
