Experiment Hunting

[P-man]

I am on the hunt for basic chemistry experiments to post on my website. Any contributions well appreciated.

Depends what you want. Go mix salt with water and put a 9v battery in it. Bubbles!!! and there is no point to explain why this happens, i can assume your intillegent enough understand. What experiment do you have in mind?

[P-man]

I just want tons of experiments to p[ost on my website. It doesn't matter what type.

Unfortunatly i prefer expirement that explode, and the titles say "...please no bombs. Too bad. Well here is some that won't kill you but fun to watch, not to mention wasteful. Learned it fromm video.google.com mix drop a minto into a diet coke (i think norma coke works fine), stand back and watch the foutain of coke shoot 5 feet in air.

Or did you have more complex and chemical made experiments in mind? I can give you plenty.

[P-man]

Anything. From complicated ones to kitchen experiments, I'll take anything.

well, as far as quite simple goes, you could take the juice from a red cabbage and then add acids (like lemon juice) and bases (like milk, i belive or soap) back and forth and watch the color change.

there is always the classic, bking soda + vinigar experiment.

hmmm....and then there is alway baking. Baking a cake has some really cool chemistry in it (crosslinking of proteins), AND it tastes delicious.

Try this for a cool experiment. Run the video when you get to the site.

The wonder of Diet Coke and Mentos... Very cool!

That movie is totaly awsome!!!!!!!!!!

heres a good experiment to make sparkles get a wooden stick dip it in pva then roll it around in a tub of iron fillings set alight to it and you have a sparkler i would say how to make back yard fire works but im not allowed

The exciting: Tris(hydrazino)nickel(II) nitrate, Ni(NH2-NH2)3(NO3)2

To a saturated Ni(NO3)2 solution in water add twice the volume of ethanol
(green solution). 50:50 hydrazine hydrate in ethanol. Drip the nickel solution into the hydrazine solution with brisk magnetic stirring.

Deep blue flocks break under the agitation and turn pale pink. Mild exotherm. Filter the bulky precipitate. Wash with cold distilled water, then ethanol. Dry in air.

Reasonably shock-insensitive. Deflagrates with flame. Detonates with confinement - 7 km/sec or 22,960 ft/sec.



The cute: Photoreduction of benzophenone to benzopinacol.

In a 125 ml round bottom flask dissolve 10 g of benzophenone in 70 ml of anhydrous isopropanol with warming. Add one drop of glacial acetic acid. Fill the hot flask to the neck with more isopropanol.

Firmly stopper, then wire or vinyl electrical tape the stopper in place - do not occlude the round bottom! The flask must be sealed warm. If it is sealed cold and warms in sunlight, expanding liquid will burst it.

Invert the flask then expose to sunlight for a week or more. Abundant crystals of benzopinacol grow as the benzophenone is one-electron reduced and dimerizes.

You could go with the classic flame tests....
Get aqueous solutions of various metallic salts and burn them in a bunsen burner on a wire loop or wooden splint.

This is a classic and beautiful demonstration of electron energy levels and the atomic spectrum.
