Bottle Volcano

Science class. Yes.
Our teacher was telling us about how the change in pressure on top of a volcano can either make it erupt or have it not to erupt. One of my friends decided to ask a question that would soon lead to something fun.



Friend: I don't understand. *asks*
Teacher: (brings a bottle of water) Okay. Look.
Me: Uh, that water has gas in it, so don't shake-
Teacher: Yes, yes, yeah. Think the cap as 'pressure'. Even if I shake
the bottle like this, the pressure doesn't let it come out.

Uh-oh.



Teacher: So, if you don't have the pressure to block the way, you-

What the fudge?!

-you get a mess.

I told her. I did.

Conclusion: Water with gas + shaking = fail.
Don't try this at home.

Test Tubes

Another fun event in science. Yay.

Let's start off with how we were supposed to make different solutions in test tubes. The teacher had two kinds: The detailled precise measuring expensive test tube and a cheap typical test tube. This is what my teacher said:

"Look here guys. Do you see these test tubes? It might not look like it, but these are quite expensive. So if you ever have to break a test tube, break those cheap ones over there, okay?"

Then she decided to knock an expensive test tube to the floor.
"Oh shoot."

Thud.

Oh, were you expecting a 'crash', a 'ka-zing', or at least a 'zip zap bobbity boom'? Well, too bad. Fortunate for our science teacher, the test tube didn't break, thanks to the safety collar on it that didn't let it break just that easily.

Then she says, "Phew. Well, I'll make sure I'll break the other ones next time."

One of the cheap test tubes decide to roll off and fall at that moment.

"Oh shoot."

Darn it. She catches it. Now that's what I call fast reflexes.
I'm probably going to end up breaking a test tube one day. You'll see.

Todays lesson: Don't make foolish promises.

BZZT!

Ta-Daa! Yet another weird science equipment. (Some weird static ball thing) This is the thing that typically makes your hair stand on its ends. It wasn't for our class, but for a different physics class. She anyways let us try it out at the end of class. It had many safety precautions.

1. Stand on top of an insulator. If on floor, you will get shocked.
2. Don't forget to discharge with discharger after using it one time. If not, the next person to use it will be shocked.
3. Even if you're the same person, don't take off your hand and put it back on it again. It does the same as 2. does. You will get shocked.
4. No one should touch one who it using it currently, or you will get shocked.
5. After you're done using it, turn it off, then get off the insulator, or you will get shocked.
6. Be sure not to get shocked.

First, the teacher showed us an example. Well, apparantly, the hair only stands up for those who don't have clumped, curly, or messy hair. So no, it doesn't work that well for that purpose.

After she was done, this guy decided to try it out. He stood on top of a small board (insulator), turned on the thing and put his hands on it.

(Bzzt.) Ah.

*takes off hand in surprise and puts it back*

(Bzzt.) Ouch.

*takes off again and puts it back*

(Bzzt.) Ow!

*you should know by now*

(Bzzt.) Argh!








Teacher: Whoops! Forgot to discharge it.


Haha. Fun classmates, fun equipment, and fun teacher.
I'm looking forward to the physics class.


BZZT.☞

Science is Fun!

In our science class, we have this shower thingy in the corner of the room in case you catch fire or a chemical starts to melt your skin off.


One of my friends was curious about whether it actually worked, so he decided to ask the teacher.

Friend: Does this work?
Teacher: The last time we used it, it did, so hopefully, yes.

So my friend went over to the shower thingamabob, and...

Lab Report

Question: Does it work?

Procedure:
1. Pull the lever.
2. Observe.

Results: Water came out.
Conclusion: It works.

Next Question: Where's the mop?



SCIENCE IS FUN! :)
