All you need for any science experiment is a Delorian and "Pimp my Ride"

not that you'd be able to do it anyway[/QUOTE]
It doesn't look that hard to make except for the vacuum part
I find that the easiest way to make a rocket propulsion system is a bit of gum, 3 grams of crushed glass and pink glitter.
I recently made a [url=http://sjackm.wordpress.com/2010/09/16/making-a-led-flasher/][b] Led Flasher[/b][/url] :D.
i recently made ferrocene.
it was pretty damn easy.
Wow, how did you do that? And what can you use it for? I found it on wikipedia and saw it's an organic "sandwich" compound, but didn't have patience to read through all of that. We didn't learn so much about organic compounds yet. This year we'll do though.
I mean, come on, this thread is for posting\explaining how we did these experiments!

it's not particularly useful but it's put in unleaded fuel for anti-knocking. it's just quite interesting.
I bought some uranium with my last money and waited a few thousend years...and you know what?! THE FUCKING HALF DISAPPEARED!

Mix bleach and ammonia (2:3 ratio) to create nitrogen trichloride, which will blow up in your face.
I once put an almond in NaOH for a week, then I took it out. A week later it had some serious fungus growing out of it. Like, mushroom style almost.

Why did it do that?

Because :science:.
Anyone have any good not too difficult physics experiments that don't include electricity?
I'm producing an iPS cell line and testing a hypothesis on the generated line.
No real details yet, I'll make a thread when things start happening. Even then, until publication I'll just be updating you guys how on my cell line(s) are going.
I'm also making a coil gun soon (unrelated to the iPS cells), but that's hardly original research or an experiment, even.
I don't think I posted this here, but in September I repaired an audio system(it had an exploded IC). And yes, only now I remembered about this thread :).
It's not really a science experiment, but oh well. It was something interesting and fun to do for me:

Mix hydrogen peroxide with bleach. It makes water and salt (NaCl), and releases some oxygen.
I discovered this by accidentally putting color safe bleach (main ingredient is peroxide) into the bleach compartment of my washing machine where there was some bleach still left in. It then started foaming everywhere.
I know another reaction with hydrogen peroxide.
If you take out some MnO2 from new batteries( old batteries have used up material that I think is Mn2O3, I think- correct me if I am wrong) and put it in some hydrogen peroxide, the hydrogen peroxide will start decomposing in H20 and oxygen. MnO2 is a catalyst in this decomposition, and it remains unchanged.
ever heard of a rubens tube? i'm building one right now in order to get out of taking my conceptual physics final :D
I've had some fun with Thermite and blocks of ice before, and I'm currently working on a tesla coil that produces music. All the other random explosions I made are irrelevant to this scientific endeavour

So I bought this Oil Burner Ignition Transformer which has 10kV and 200W, which is going to be used for my school project (a tesla coil)
Something I did one time I was observing some chemists at the local uni is that they where testing the oxidising ability of Dioxygen difluoride. BTW do not do this at home, I only took a very small part in this because I'm not a chemist just an aspiring to read Pharmacy/Pharmacology at uni one day. So we passed fluorine and oxygen through a tube heated at around 500K and then they tested it on a few substances. T'was all very fun to watch!
A good thing to read about this substance is here:

Get a force meter. Find a ring with known diameter.
Put ring in fluid. Measure force when pulling the ring out (the peak force).
Calculate surface tension.
Repeat for different temperatures, fluids.
Such is the life of a physicist :frown:

i find this difficult to comprehend
This thread consists of about 99% electronics and science talk yet only 1% of anything here was done by a person who followed the scientific method.
A dead simple demonstration of Bernoulli's principle:
Go to the kitchen, get a spoon.
Run the tap at the kitchen sink.
Hold the spoon by the end of the handle in such a way that it's just hanging from your fingers and is able to swing freely.
Now, slowly advance the the spoon towards the running water. Watch what happens when the bowl of the spoon comes in contact with the stream.
Why is it so?
Bernoulli's Principle states that when a fluid accelerates, for instance when it goes through a venturi or past a wing, its pressure must decrease. Therefore when the water passed over the curve of the spoon a pressure differential was created and the spoon moved further into the stream.
Even simpler: get a strip of paper. Blow over it. Done. :P
Repeat newton's laws of motion, drop an apple for a tree.
Result: Prove or disprove laws of gravity.
[b]Smoke bomb:[/b] Get some Ammonium or Potassium Nitrate (a common plant fertiliser) and heat in an old saucepan with sugar, until you get a paste. Add natural food colouring for best effect. When you burn this stuff you'll get a serious amount of smoke.
[b]Stink Bomb:[/b] Heat Iron and Sulphur together, sulphur dioxide will be given off. Serious rotten eggs smell.

Anyone know what frozen orange juice, detergent, and gasoline make? lol
Chlorine and Ammonia?

They make death

Better yet, fill a beer bottle 3/4th's of the way with an equal mix of gasoline and alcohol, then fill it the rest of the way with crushed up Styrofoam. seal off the top, then duct tape a storm match to the outside. Strike match on a rough surface and throw.
Soviet Style Molotov Cocktail. :buddy:
