Wavy hair making products.........any good ones?

[Demon]

Going on a night out on Friday and wanted a different look for my hair. My hair is medium length straight hair and I fancy having some waves in it. I don't want anything permanent like a perm just something temporary for the night. Don't want crimpers though. Anyone got any suggestions and don't forget that I will be doing it myself!!

Looking forward to reading your replies. Thanks in advance.
