Things that you need to know.

1. Know what you are doing.

2. You need to know what you are doing.

3. You really need to know what you are doing!

4. Overconfidence kills you.

5. Stupidity kills you.

6. Playing with hydrogen ignorantly kills you.

7. Even when you spoof, stupid can get you chemically killed..

[Damocles]

Its a spoof. But HCL is colorless and relativley odorless. It will eat your face off. IOts an acid.

8. Ignorance of chemical symbols can get you killed.

9. There is a reasoin we need to institute a keeper corps to mentor the mentally not so capable!

How to make rocket fuel.

[Damocles]

Rubidium and cesium are not stuff you play around with. Here's why!

cqeVEFFzz7E

Alkali metals can kill you.

[Damocles]

Have you noticed how many ways chemistry can kill you?

Chemistry for Easter.

[Damocles]

-ElTyzqkWWo

More Easter fun-this is DEADLY though. No Kids at all.

[Damocles]

VcFOBxbLisg

More Easter fun. Again NO KIDS! There is no such things as safe chemistry with dry ice or kitchen detergents.

[Damocles]

jgvL2sX_FhI

Polymers-(elastic plastics-what you are made out of)

Any questions? Kids can make this under supervision.

[Damocles]

And one more.

Y71u18_Euxg

Dangerous. Some kids have attempted this in themselves. Pay close attention. Menthos and coke inside of you is a guaranteed funeral. You don't burst like a balloon, but you will rupture something internally and you will DIE.

This is how NOT to get future chemists.

[Damocles]

bamLUuCNvJY

Remember the bungled inverted flask experiment? This is the same thing done right!

[Damocles]

wB5UDnvi9uI&feature=related

Molecular chemistry. Flax can do this!

[Damocles]

D717oY4WyhI

What does static electricity have to do with chemistry?

Well all chemistry is electromagnetic!

[Damocles]

d2jaGKF0rfA

The answer is surface tension or the coulomb force in water. Its that same thing I've been showing you these past experiments.

[Damocles]

Water is weird.

pTdiTe3x0Bo

A metallic alloy is supposed to do that!

[Damocles]

Water is weird.

Z1kEgWJYNL4

http://en.wikipedia.org/wiki/Diamagnetic

Metallic alloys do that!

[Damocles]

Pb69HENUZs8

And what does this have to do with chemistry? Coulomb forces hold liquids together but are so weak that they cannot affect flow! Gravity and angular momentum of a large mass is stronger!

[Damocles]

Water is weird.

VGoJuLX3BQQ

Solid steel is heavier than water. However coulomb forces can cause sufficient surface tension to float a paper clip. Watch what happens when some JOY(TM) enters the equation and fouls up the local charge orientations and states in that metallic alloy.

[Damocles]

VYUUnQe2HV8

Endothermic reaction + kids = reasons to be cautious.

[Damocles]

Wf9GWp2KRVA

Even when they know what they are doing, Human beings have to be careful with the simple stuff. Dry ice is simple.

The lesson is that dry ice can kill you.

[Damocles]

AEXsBg7uVSY

Thermite and morons don't mix well. Remember, in trade schools and the army, we train young teenagers how to use this stuff safely, so what is this guy's excuse?

[Damocles]

fpXriHXHaX0

There is something called sympathetic detonation. Shockwaves can set off a chain reaction.

Yeah, chemistry can be exciting.

[Damocles]

aeuT_oi_aQ8

Bang. Gunpowder is dangerous.

[Damocles]

chkZZ24Zc0I

That was a SAFE amd well conducted demonstration. It should tell you something.

[Damocles]

WkDCS8xeobg

There was an example of applied chemistry that didn't work.

[Damocles]

__1Ym_F94CE

Get the point? I work with dangerous stuff every day. Handling it is boring dull and repetitive step by step procedure-based on the long experience by every goofball who has hurt or killed himself before me. But if you don't stay alert and do the procedures bn the numbers, you will DIE.

It helps you; if you understand why you don't pour into a fire for example.

[Damocles]

Speaking of KABOOM, here are some Darwin award winners who played with chemistry and hurt themselves badlly.

LOMaXHcZqyM

This is a controlled burst menthos soda bomb. This is dangerous.

[Damocles]

WS8iF_7lWUk

This is just baking soda and vinegar. Note the result.

[Damocles]

The young man's comment......

Blew my friend's b---s into shreds.

[Damocles]

Dry ice bomb.

1AM-AeGsxS4

[Damocles]

This is a radio boosted dry ice bomb.

0yqCYtvZmDU

The experiment was conducted under controled conditions.

[Damocles]

Hairspray is an explosive.

[Damocles]

WD-40 is an explosive.

[Damocles]

One more time.....WD-40 is an explosive.

This kid was peppered with plastic spall and had deep cuts and bits of plastic embedded into his face.

None of this is funny or hilarious. One of these ten people you just saw DIED as a result of his injuries.

The point is that you need to learn what your chemistry is so that you do not accidentally mix household chlorine and vinegar or ammonia together and kill yourself with poison gas or put baking soda and salt and another chemical (vinegar again) in the wrong proportions and blow yourself up.

Read your warning labels, and if you don't understand, DON'T USE. Its no shame to ask for help either from somebody who does know. Any age or any person, ignorance of something can kill you. LEARN.

[Damocles]

Today is model rockets.....

96vxvpuWzuI

Not a b ad demonstration. i wasn't to crazu about the unsafe lighting procedure. That flame gets hot enough to melt tin.

[Damocles]

UyWPNhcI-jU

Safe launch, but note what happens three seconds after ignition.

[Damocles]

v-PG3agMFKw&NR=1

Model rocketry is an adult undertaking. Homemade rockets are not for the careless.

[Damocles]

SG9iUsEepQ0&feature=related

Done the right way, it is a beautiful experience.

[Damocles]

D6tCVSNb5P0&feature=related

This was a failure.

[Damocles]

cuKKzG-JFWw&NR=1

That was a success.

[Damocles]

Qs6r7ldDgj0

Fructose, iron oxide and potassuium nitrate, called an R-candy. It ddn't blow up. means this gonzo has tried at least a half dozen static starts or test firings and hasn't lost his hands so he's just becoming confident enough to try stupid.

Note that he is too close to the rocket?

[Damocles]

H5T8o1VxYBU&feature=related

Big version. These guys ran behind a berm.They've been doing it for a while, so they know better.

[Damocles]

rF1RE2Kb2Lw

Don't sneer at these guys. Their rocket outperformed expectations by at least one order of magnitude. Simplyn incredible that they masted a compound boost to suatainer motor is a single candle. We didn't fihgure out how to do that for war rockets until about twenty years ago and these guys duplicated it on their own just by trial and error?

[Damocles]

ZQeCQ2Zdj18&feature=related

Rocketry lesson.

[Damocles]

4pTUeuEv8Uc

Another pair of big kids. They don't allow guns in Australia but apparently any NUT can get hold of a jet engine and rig it up in his back yard. That big engine is a BOMB. If it failed it would take everything within 150 feet with it straight to blazing glory.

How smart those two geniuses are can be seen from the one guy walking across the exhaust plume of that RR Derent.

Can you say kicked up rock or nail?
