how do i do long spiky hair like this!!!??? (pics)

You're going to need some serious goop to get longer hair to stick out straight like that.  The general idea is that you put some goop in it (gel would be firmest), then you let it dry, then brush it out.  This puts a good coat on it to help it move the way you want, but don't repeat that step or eventually you'll get tons of white flakes as the gel starts to peel off the hair when you brush it. Then hold it out the way you want it and spray it and let it dry in place (a hair dryer will help speed up the process, but hold it far enough from the head so it doesn't move the hair as the hot air passes over it).  If you move the hair when its still wet, it will look wet when it dries, not like the photo above.  Then add more light coats of hairspray after it dries in position, always keeping the spray far enough from your head to not make the hair get the wet look.  Its tricky to do at first and get it looking not too stiff or not wet, but you'll get the hang of it with practice.

ooh ok thanks a lot, i should try it sometime.. is there any specific gel/hairspray that i should use? and if it doesn't work.. should i use hair glue or elmer's glue that i've heard so much about on the internet?

Garnier Fructis Fiber Gum Putty :]  just for mohawks and the like... i hear it works great

I definitely wouldn't put Elmers glue in my hair.  If the hair products don't work, you could try the jello, (and when I had a punk boyfriend he spiked his with eggs somehow), but I wouldn't go for elmers until I had researched how easy that would be to remove.

ok i'll try it.. i hope it works since my hair is like 7 freakin inches heheheh but i want that awesome hair style lol ok thanks :)
