It's a bird? It's a plane? No, It's a water rocket.

All the materials that are required to make the water rocket.

First step, cut off the bottle.

Then, plug the rubber cork into the bottle's mouth.

Place the nose cone at the bottom of the bottle.
The water rocket is done and is ready to be launched.

Building a suitable base to launch the water rocket.

The base is ready.

Pumping air into the water rocket.

I'm wearing rain coat while pumping the rocket.
(Takut kena lumpur.)

The weather is not so good leh, fast fast launch the rocket lah.

Finally, we launched the water rocket.
It is flying, can you spot it?

Water rocket is above the tree.

Since you can't spot the water rocket, with the help of technology, we highlight it.
It is clearer now?

We forgot to take group photo.
But never mind, i still have this one.
Chang Yeu and me.
(Both also kend mud)

This water rocket is not for play play purpose only. This is our group project for Advanced Applied Mechanics. Anyway, it is fun to build this thing up. But the worst part is, we have to do a lot of calculation and a presentation about our project. These part is what i consider as not fun at all. Wish me good luck in the presentation lah.

The end.
