If you're impressed by Mentos and Diet Coke, it's probably because you've never shoved an Airborne into a Cherry Coke Zero can.
There might just be a reason the Airborne doesn't fit without first being broken into pieces - because it's not something you want to do.
By the time I was able to get to the can to start slurping off the foam, half the can had oozed out onto the table. A sad, sad night.
On the other hand - a Berry Airborne adds a nice taste to a Cherry Coke Zero.
