What is a fun/interesting science experiment?

sucking an egg into a glass bottle... that's always cool. or just steal something from mr. wizard

People laugh at me when I tell them, because its not as cool as model volcanoes or anything, but my absolute favorite science experiment in elementary/junior high was the one where you put a potato in the dark, and after a few days/weeks, you can see how the roots grow towards the light.

What you do is use a shoe box, or something a little bigger, but something with a lid so you can see what kind of progress the roots make. You stand it on its side, and place the potato at the bottom. Then you make sort of a "maze" out of the shoe box. Cut scraps of cardboard, place one right above the potato, tape it down, but leave room on the other side of it, then put another piece above the opening, so on. (its hard to describe... but really its just a maze, like the "find the way out" puzzles in newspaper.

anyway, the roots will grow through the maze towards the top of the box because thats where the light source is. So when you take the lid off, you'll see the roots have twisted and turned around the corners. Its really cool.

Like I said, ppl think its dumb, but I hate science and I thought this was a lot of fun.

making slime....using pva and 4% borax solution.....always fun!!!!

I remember making the 3 different types of rock using grated crayons. You put some between some aliminium foil and then inbetween 2 boards and sqaush it in a vice ( for sedimentary hmmm wait maybe it was press it with hands in the foil for sedimentary and the metamorphic was the vice.

I remember the igneous was when you put the crayon filings and foil into v hot water for a bit and then take it out....waiting till it cools down and looking at them...then comparing all 3.

those are not actually experiements as such just fun things to do........

making copper sulfate crystals

it rocks

Get a beaker or vessel that can withhold acid-salt solution for a long period of time.

Get some copper such as wire, copper coins, other copper scraps.

Get household diluted acetic acid (white vinegar) that is double the volume of the copper.

Get a sodium chloride (table salt) that is equal to the volume of the copper.

Mix the diluted acetic acid and sodium chloride in the beaker until the sodium chloride is dissolved.

Add copper to this diluted acetic acid and sodium chloride solution.

Place beaker in a dry dark area.

Wait about four weeks for solution to turn blue and then take out copper pieces.

Wait about another two weeks for water to evaporate.

Then you will have made copper sulphate.

Make a solution of salt water. Attach paper clips to the two ends of a 9-volt battery, and put the other ends of the paper clips into the salt water. Watch what happens (some sort of electrolysis reaction - I have NO idea what is going on in the reaction though). It's pretty neat and might be interesting to find out what the heck is going on in it.

Thermite is allways fun,

Aluminium powder + iron oxide powder (magnesium ribbon for a fuse pretty and fun)

Make sure to do on a brick or something or ittle burn clean throught the table :P the first time ull do it it will crack the brick the second will refuse it.

And the resulting metal is magnetic

Plus safe enough to used behind safty screens with saftey goggles

the mentos in cola is always fun!

there's alot to be learned and everyone can get involved

for more information try watching some videos on youtube

hope this helps, i admire you more tryin to make science interesting for young people.

Egg shells dissolve in vinegar and the membrane expands. When the transparent egg is place in corn syrup it contracts.

My hubby just suggested lighting farts but i dont think thats too safe to show a bunch of teenagers!

There's soo many out there so here's a site where there are a butt load of them and more and about pretty much anything. www.wonderhowto.com www.instructables.com
