I told Kale we had to wait until the weekend, so that Kris could take Bea and I could give Kale my undivided attention. The thought of things exploding with anything less made me a bit nervous. So first thing Saturday morning (and not a second later), we got to work!
So there weren't any actual "explosions," but I think I'm the only one that was disappointed by that. Kale was more than happy to watch the "lava" pour out from the top over and over and over (until we ran out of vinegar).
Now we have a permanent volcano that we can fill and refill as much as our hearts desire and I can lay my volcano impersonating days to rest.
