Flutterby™! : Boom

I'm wanting to do a longer edited version of this, because we've got some good footage, but... Yesterday, Forest came over to hang out. We wired up some valves for the irrigation system (it's amazing how much easier crawling under the house is when there's someone at the hatch with a flashlight to commiserate to), did some work on the kitchen cabinets, and then decided to have some fun. We went down to the local mini-mart and got a 2 liter of A&W, brought it home, drilled a hole in the cap, put a bike tube valve through the hole, filled it half full of water, pumped it up, turned the cap off, and the thing launched out of our front yard and hit the telephone wires. Hard. And the neck of the bottle was all flared.

So we filled a cooler full of water, got in the car, went to Albertsons, bought a bunch of the cheap soda, and went to a local park. Did a bunch of launches, had some fun talking with people there, but after a while kind of felt like we should give the park back to other people, given that with our lack of aim a full quarter to a third of the city block was "down range".

However, the day still wasn't "over", there was no big culmination to playing with bottles at 100+PSI, so we decided to pump one up 'til it exploded. We pegged the meter on my bike pump, which goes to 160PSI, and still no boom (From previous experiments, I expected the cap to be history at about 120PSI), so, with the camera rolling, I grabbed a screwdriver, and from a safe point, dropped it.

Here's a little video, I'll do some higher quality (with a little more context, if everyone involved is okay with appearing in pixels) later. Yeah, we were kinda shocked we didn't have police cruisers in the neighborhood shortly thereafter.
