How do I make lip balms with flavours like Skittles, cherry coke, m&ms etc like Lipsmackers?

I really want to make my own homemade lip balms for presents, and rather than just buying them from the shop, I think it would be fun and more thoughtful if I made my own. I really want to make nice flavoured lip balms, but don't know what is needed to make such flavours. Any help is great, thanks :)
