like dropping a marble in a tube and using different liquids to test the viscosity!!!

one generally uses pure water as a base point. other liquids are typically refrenced as lighter or heavier than water.

Hi - here are some ideas without seeing your actual data.  First - the system was too hot during transfer to  the membrane - be sure you aren't running it at too high  a voltage.   Second, not an issue with the  blot,  but with  the gel  - was it expired?  not fully polymerized? were the  wells free of debris when loading  samples?   sometimes with highly concentrated samples, especially cell lysates,  this  can  happen  because  of  viscosity  in t he  sample  (from  DNA for example). good  luck.

there are a few diff ways for this.  the way i do it is with a rotating lazer level. you can rent them at most rental places, another way is with a transit/builders level but if you dont know how...you will be lost cause you wont know how to read it. or the cheap and easy way.   get some clear plastic hose hold the ends up and fill it with water. create a "benchmark". use a post or somthing else you can tie it to and walk away without spilling. on the other end make a leg for you to rest it on roughley as high as the post. now as you move around you can see if it isflat by marking the level in the tube cause water will seek its own level. i prob left out some things in the explanition but im sure you will pick it up.....it was good enough for the romans and it can work for you.

make sure you know the material you are being tested on

Decent idea:\n\nTLC with m&ms.  I did this once for a "show and tell" to an 8th grade class, and it worked great.\n\nUsing coffee filters cut into strips, water, plastic cups, a Q-tip and different colored m&ms, you can spot the dye from the surface on the m&m onto the coffee filter and then place it into a shallow cup of water.  The water wicks up the paper and carries some of the color at different rates.  \n\nRed m&ms show 2 red spots\nBlue m&ms have 2 blue spots\nPurple m&ms have a red and blue spot.\n\nIf you don't want to do m&ms, you can use ink from a narrow tipped marker.\n\nGood luck!

i think my brain would implode if I attempt to even think about thinking of every word I know.  Tried for a moment and I went a little wacky.  Well, maybe it's the glass of pinot i just downed that caused the wackiness.  oh well...it was worth a shot.

I am a seventh grader and once my class had to do a report on some of the experiments we had conducted in our school laboratory. The girl who sits next to me didn't know what to write, so I told her to write that our teacher had caused a nuclear meltdown in our lab! The poor girl obviously didn't know what nuclear reactor or meltdown meant,so she fell for it; hook,line & sinker! The best part is that she actually submitted the report to our physics teacher! I was on the ground, howling with laughter. The experiment was actually about heating a metal ball to show expansion.

I remember in first-year university when a bunch of people went for an experiment where they did that, and I believe they said it would take about 8-10 hours for them to go back to normal. I remember it was kinda funny, I had a class full of people who couldn't see the presentation!\n\nHonestly, I wouldn't worry about it at LEAST for another couple of hours. If you know the name of the drops they put in you could search the web for a timeframe.

Could you try the old idea of different types of liquid in a clear glass/plastic tube. Each has a different density, so the heaviest goes to the bottom, the lightest to the top? Cant remember the exact liquids to use, but something dense like oil, then baby oil, water, etc.....the tube can be shaken, but the liquids will always seperate out in layers......

put them in quotes.  "fluid statistics"

tiny amounts of chemical can stick to differnt things, like stir bar, stir rod, thermometer and if you remove these items before the experiment is over then you remove some chemicals.  Other kinetics events that your not considering. as in pressure, humididtym and so on.  If you used a Ph probe then maybe it wasn't calibrated right or isn't properly maintained

You need a variable in any experiment to compare results. Perhaps you could use cold (ice) water in one container, warm in another and hot or boiling in another. You can then make your prediction on which will dissolve first and have an experiment that will verify whether you have made an accurate prediction.

could be lime diesese ... not show but the same thing happend to this girl on the discovery channal and she got tested once and came back neg. but the next time she tried it was pos.    maybe that could be it!

It's bernoulli's principle. Fluids have a lower pressure when moving than when still. Since the water is moving past the spoons (which act like the wing of a plane) they feel a pull from the pressure drop and come together. Try it with a peice of paper sometime. Roll a piec of paper up so when you place it on a flat surface it looks like a curved bridge. then blow under it and it will collapse instead of blow away. It's pretty neet.
