Sound

[groovy chick]

which five things can sound travel through?

[Hamish]

sound can travell through more than five things, ie wood, glass, air, my head, paper, steel, copper, concreet, sponge, cheesecake, bodyparts........ If this is a homework question perhaps you should give some context.

Sound, however, can not travel through a vacuum. So it wouldn't be able to pass through your head, groovy chick.

haha, scathing words. her username & the nature of the questions indicates that she's probably doing her GCSEs so don't be too mean

There are five states of matter, solid, liquid, gas, plasma and Bose-Einstein condensate which occurs at very low temperatures and is a super-fluid gas (but I'm  sure you all knew that.)

jake-the-peg, I am most grateful for that information. No more Christmas cards for Deborah Jin, Markus Greiner and Cindy Regal though. You think you know some folk inside out and then they go an discover a new state! Did they let me know? NO!
