This reminds me of something I did recently. IIRC, I made bubblegum soda. That might sound revolting, but if you give it a try you will like it too. For some reason, it tastes good. I think the mixture is:
A&W
Coca Cola
Strawberry Fanta
Squirt
Strawberry Fanta and Squirt make the flavor of it. The reason you apply it to the other two is because I found the base feelings to have the taste span of a ball of bubblegum. If you use the flavor for anything else, it tastes not like bubblegum. Coca Cola and A&W make up the base feeling of it. Don't know how to describe it.
