I need to learn how to make hair gel?

I need hair gel tonight, because my volleyball team is all wearing the same thing tomorrow, but I ran out of styling gel and it’s too late to go to a store to get more! So I want to know if anyone knows how to make hair gel without any weird ingredients. I found some ways online, but they either have funny chemicals or they have unflavored gelatin… But all I have is Jell-O! So if you know a way please tell me!(: Thanks guys!
