The Whoosh Bottle

These "sometimes" explode... if it were to explode, glass shrapnel could kill you if it goes to your neck. Source: YT

That's quite awesome. Really like the variety of shapes the burning gas takes, particularly the bumpy upside-down pie platter thing about 1/2 way through the video (shows as a thumbnail for me as well).

I actually did this as my high school chemistry project. I used 70% rubbing alcohol, 90% rubbing alcohol, and pure ether (don't try that at home, kids). You can get a number of different effects, only some of which were seen here.

As I recall, there were 5 distinct effects I noticed.
First, and most exciting, the jet. This was just a 2-6 foot jet of flame out the top, I surmised it was caused by low oxygen inside the glass making for a poor partial burn inside until the pressure pushes out enough unburnt vapor to burn outside. Depending on the fuel (both vapor level and fuel type), this could last up to 10 seconds.
There's a 'neck burn', where the flame hovers just inside the neck and just burns there, apparently in equilibrium, like an oil lamp.
There's the fire ball, which is just as it sounds, a round ball of fire, usually hovering in the top 1/3 of the bottle, sometimes bouncing up and down, but always centered.
There's the flash, where the entire interior flashes repeatedly, as seen in this video. This can end much more violently than it did here, 'pinging' the bottle loudly as the flashes get more powerful. When this happened with ether, we stopped, afraid we were making a glass bomb surrounded by high school kids.
Finally was the fire plane, also seen in this video, which can ascend, descend, or hover in place. This was my favorite effect, especially when it hovered and lasted up to 30 seconds long.

Good times, good times....FIRE GOOD.

No wonder you're a twisted firestarter, drinking all that rubbing alcohol

There is no way that thing is exploding. Show me ONE example. I guarantee it cannot. There's a big opening at the top for the pressure to release, and the glass is thick as hell. It's not going to build anywhere near enough pressure to explode. It's round for a reason. These things are hard to break even dropping them.

I used to do this at parties as a kid all the time with glass beer bottles. I tried a plastic vessel once, and while it does work, I only recommend doing it once and allowing the plastic to cool completely. Using zippo fluid and a plastic bottle repeatedly will eventually cause the plastic to heat to an unstable temperature producing a catastrophic failure with disastrous effects to your mother's carpet.....for science.
