If you can find a empty glass gallon jug, from apple cider or something like that.
Find a egg larger then the hole in the top of the jug, boil the egg.
To show how air pressure and vacuum works peel the boiled egg - drop a lit match into the glass jug - place the egg over the opening and watch the egg squeeze through the opening into the jug! You may need to use burning paper rather then a match it burn up more air in the jug.
To get the egg out of the jug, invert the jug so the egg is sitting on the bottom over the opening of the jug - place the jug opening over your mouth and blow into it, then quickly move it away from your mouth, as the egg will quickly squeeze through the opening and pop out, going into your mouth if it's still there.
Quick easy and a real science project.

well there are three things i can think of.

1.show the mass of gas by putting a tablet of alketcelser and mixing it with water in a jar sealing the cap and getting before and after mass before the tablet is mixed with water and after it is mixed with water.
2.get a bunch of different liquids and put them in a graduated cylinder. then the least dense liquid will be on top and most dense will be on bottom. this is a great experement. color dye each of the liquids to tell them apart :)
3.ok this ones a fun one. to find the difference between these 3 liquids methenol, ethenol, and isoprphenol. Now these three alchohols have the same mass and density so theres no way of telling them apart. so you can find there boiling points freezing points and melting points. teachers love this one.

I recommend you use the second experiment i gave u. this ones simple n easy and it is very colorful :)
