Any scientists here? I need some suggestions :-)

Mass spectrometer and a particle accelerator and see if during those reactions you can get anti quarks.

Otherwise get a microscope that works at 100-10nm, should look cool.

Actually this is nice suggestion. To get back to Krazy's assignment, you can report your findings in terms of the altitude your toy rocket attains, as a function of acid concentration, acid temperature, and powdering the solid.

You need a good altitude measuring system though (radar?).

lol i could even do a video recording, and use my brother instead of me as the test candidate :-)
somehow i don't think the teacher will appreciate it though :-)

however that rocket sounds interesting, i've done similar experiments, but not from this point of view, in finding/testing/measuring chemical reaction speeds.

thanks for the ideas so far

cheers

<font color=red>What should i put here!</font color=red>

Not that I'm really suggesting this, but an experiment using dry ice bombs might be entertaining.

<b>FireFox 1.0.1: Works for me … You’re on your own …</b>

Didn't they use to have frogmen or submarines that used to work on that principle?

Used to have clear glass bottles of milk and these things would go up and down based on bubble (CO2) production.

Some sort of pressure measuring device

You could measure the height of the rocket with a tool to measure the angle. Use trigonometry to figure out the height. (left as an exercise for the student).

The loving are the daring!

I dont want to be the one to piss in the punch.....but how accurate could you be with simple trig? Wouldn't it negate crosswinds and even a small error in gathering the angle could result in a large error in the total rate of change at the end.

Why not get some lgithweight fishing line and set it up on a spool that will allow for quick release. When it pauses thats your height. Each bottle or rocket would have the same small weight of the fishing line....and therefor would be no problem.

I tryed measuring the height of things from a distance using trig. The actual numbers were off by a decent %.

Just a little heads up on some possible problems. Its all about the equitment that he can get a hold of and what kind of detail he really wants in this experiment.

__________________________________________

I measure tall objects, like water and cell phone radio towers using trig, and it is very accurate in its method.
But a rocket woud drift, and this could skew the measurement a good deal, and would not be very accurate for height comparisons.
You could use a fishing filement, or just time the flights. Either would give you a repeatable measurement.

Well I think that one aspect of the experiment that will have to be worked out is, how should he determine when to release the rocket. One form of the two chemicals vs the other will affect mixing rate and time till release must be constant in order to get accurate results.

That wont measure reaction speed. If he were to measure time to reach a predetermined pressure and then pressure reached by a predetermined time he would meet the criteria requested by his teacher.


I am going to get away from the desk for a while, be back later.

If the rockets are not too powerful u could get them to follow a guide. The guide could be a dowel (or several connected. It could be a fishing line strung to the top of a tall structure. You could even lauch horizontally and see how far it slides. (friction cancels out since it's only comparitive measurements). Slight angle so it slides back down or makes for a smaller demo layout.

Make it spin a wheel? Count the revolutions. Not too bad if it doesn't spin like crazy.

Propel something in water. See how long it takes to displace water.

Hello again,

Well help is what I asked for, and help is what I got :-D Thanks for all the comments and suggestions, especially in such a short amount of time, much appreciated.

First, the level of detail that some of you are talking about, really, probably wouldn't even be noticed/appreciated by the teacher at this stage, or i should say, won't get me extra marks :-) however, I doesn’t mean I won’t do it for my own sake. :-)
I like the idea of the fishing line to measure the hight, and then, for myself, I wouldn't mind playing a bit with the trigonometry, see how it works a bit, and how accurate/inaccurate I can measure compared to the fishing line.
I can even record it all in my (pain in the backside) logbook I have to write up and submit; also, it may look more impressive and like I actually put some work into this even if I do get completely dodgy results. :-D.

Second, I do not actually ‘go’ to school. I study via correspondence, so a lot of my work is sent via mail for marking, along with audio tapes, and possibly a video tape if not too much hassle. However, it means I am at a slight disadvantage with easy access to proper equipment, though I probably can get/borrow stuff from my local TAFE if really necessary, though it would all be under supervision.
That’s why I like this idea of this 'rocket', as it is fairly easy to DIY, without going out of my way to much, and just using a little creativity :-)
This is my final ‘preliminary-science’ subject’s assignment, which I need to pass before I can go study/sit for certain HSC subjects. And then after that, I can possibly take science, in some form, seriously, on into university. So at the moment, what is ‘expected’ in order to gain full marks, is not too complicated and high levelled science/chemistry yet, but I am required to show understanding and some proficiency.

But also, in my situation, I have limited time, as I have much else I need to do with other study (sigh) and other things, so this particular item cannot get to be a too huge undertaking and cause me to lose place in other just-as-important area’s :-).

I have to write up my Investigation Proposal Form to send to my teacher for approval over the next couple of days, and to ask for equipment that I need, etc. So I’ll need to figure out exactly how I will go about doing this and get it all fixed up. So thankyou all again, for the help and the nod in the right direction; now I have to do some work for a change :-D

As a by-the-way, have any of you guys watched the film/movie “October Sky”, a good movie, and follows a very similar slant to this rocket experiment and how you guys are suggesting to go about it. If you’ve seen it, you know what I am talking about with the rockets :-)

Well . . .
I need to go some sleep down here, it’s very late at night, and the sun doesn’t rise for another few hours.

Thanks again,
KJ

You can still get those but only in an adult toy store. I think they come with lube.

Rember that a young man started this thread and will be reading it.

Apply all your chemical combinations you just mentioned inside a closed plastic 2L bottle and shake vigorously.

Wait don't do that or you will have no hands left to finish writing your assignment.

Who in Hell do you think you are coming in here trying to get the Tom's hardware guys to blow themselves up ???

Take those mixes you are playing with and shove em where da sun don't shine.


P.S ... Stop reading how to make a bomb material off Google!!

That is why the chinstrap on a military helmet is designed to fail under a certain amount of tension.

WWII American helmets and Can Helmets as well as German helmets all had a metal link on one side that would snap if you were close to a compression wave such as that formed by a grenade blast or any other type of air compression formed by any type of blast. The chinstrap would fail and your helmet would fly free of your head and not snap your neck.

Carbide Cannons!!! What fun!!!!





Dazzle them with Brilliance, or Baffle them with BS!

Oh yea.... We played with carbide... Fun stuff...

I also played with (heaven forbid) quick silver as well....

If you agree with Sod one more time.....

What if you added alcohol to the experiment? Not as far as mixing it with the chemicals, but rather mixing it with your blood, through the stomach, of course. I wonder what my signature is. We used to make "Works" bombs. It is Works toilet bowl cleaner (with HCl in it) and foil. We once had two hot air balloons land behind my parents house, drew quite a cloud. Had to toss one of those bombs in the bushes when no one was looking! What fun!

OK, my sig is still cool!

Why should I vote when my choices are a douche and a turd?
