I Can't Believe We Did This

Or that Peter did this.
Have you ever heard that if you put a few Mentos in a bottle of Diet Pepsi, it'll create a geyser?
Peter just had to try it last night in the driveway.
While it didn't create the 15-foot carbonated fountain he expected, it did shoot out a few feet. I was impressed.
Luckily it's raining now, so the sticky mess all over the driveway is being washed away.
