There would be an explosion of Magic Bubbles! Just kidding, they would compete all the way down the drain.
You would no longer have either one
it woud froth-up and you'd have a very clean drain.
You'd be out at least 2 dollars...
Don't even think about it,scary scary stuff.
you would have sweet, rust free drains that need to be burped
You could easily upset the ectoplasmic vortex of several subatomic dimensions.
It would swirl to the right, then swirl to the left, then go down the drain with no swirl. Watch for flames.
The Coke and Pepsi would go down the drain.
I don't know!!!!!
you would be minus 1 pepsi and 1 coke
