Today I want to tell everyone that I went to an event and made a small rocket launching machine.

There is a teacher teaching us things about making this machine, and how a nerf gun works, also about someone making a big nerf gun.

I think the event is very fun because I learned a lot, and I also made this machine, I think this time is worth it.

There are some bad things too like I think the teacher should talk about Bernoulli's principle, because he thought that we will fall asleep when he explains it, so I think this is the bad part.

I think today is a good day because we made a rocket launching machine, and it uses the air to launch.
