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.

I don't recall any stormtroopers getting taken out by arrows. Blasters, all the time, so their argument is still valid, but I don't remember arrows... In fact, I thought they specifically showed arrows bounce of them, but maybe I'm thinking of the ATSTs

Erm, most dog fighting was catching someone by surprise and bouncing them while retaining energy. All things being equal, the plane with the superior energy and no other intervening factors (1v1) will win purely because the opponent always ends up lower and slower, and can't make up that difference. The jet engine significantly increased the available energy to a plane, but the F35 won't be jousting against prop driven fighters...

You say the F35 is faster, but that is irrelevant (unless it's running away), energy is a heck of a lot more than max speed, and that's where the F35 is a turkey. Lift, drag, power to weight etc all factor in. The F35 is a classic Frankestein's monster, asked to do far too many things, and in that process compromising and contradicting itself constantly.

It's kinda telling that you say as soon as this plane get's in trouble, a squadron has to drop everything to run in and help it... For this sort of money, the plane shouldn't need help, particularly not from the grandpa's of the fleet.

That's so awesome. Impressive to see her get it wrong and just get back up. Amazing the way kids bounce; any one of those would be a season ending injury for me.

And I know they could be testing me
The data might be wrong
A preplanned concocted recipe
And played up all along
But at least my graphs are beautiful
With sigma 5.1
This I know
This I know

They told me don't worry about it
Analyze the chirp and
No more
They told me be careful
And doubt it
But I've seen a merger
Of black hole-ole-ole-oles!

Quads have quite a bit of ground clearance. I wonder if letting it roll over on top of him (gently, not letting it bounce) would have been an option. Piled up the wood to either side of him in case the clearance was too tight.

Also, throwing his helmet down at the trail was a stroke of genius or a gargantuan portion of luck...

The first thing you need to understand is the suspension doesn't use springs or shock absorbers. The whole thing is linear electric motors on each control arm. (Great huge solenoids) The suspension moves up and down independent of weight or inertia. It works fast enough that it starts to compensate for bumps BEFORE the tires hit the bump.

This system has more in common with a 1965 Impala with hydraulic rams bouncing in a parking lot than a conventional car suspension.

For the most part, it scans the road ahead.
See a dip down? Extend the wheel.
See a bump up? Retract the wheel.

I'm fairly certain the ollie was manually instigated by the driver.
Much like hitting the turbo boost on K.I.T.T. it's just a button and the computer does the jump.

Press button:
Retract the wheels, starting with the front. (to maximize suspension travel)
Push down hard on front, then rear wheels. (Launch car up)
Retract front then rear wheels. (tuck the wheels up)
*car passes over 2x4*
Push down on front, then rear wheels.(ready for touchdown)
*tires hit pavement*
Retract front, then rear, wheels slowly to absorb impact.

I prefer to bounce. Cue the music!

I love how they do the same bouncing-chasing hop that dogs do.

I sent this to my brother, who is a complete nut in his approach to pinewood derby cars. Artistic and over-engineered. He has a GRAND time.

His response to me:
I enjoyed his presentation.



I went one more step. Our track at church is not perfectly machined aluminum but is instead bumpy wood. My cars had a suspension system cut into the very thin wood. They would not bounce. People suggested a fund raiser for a new track. I said, "No Way, I like that track."

i wonder if it needs to be wet and slushy more and get really into all the joints and metalwork, rather than really cold and dry causing the salt to bounce around a lot ?

I want to react seriously but the "Oh my God! OooooooH!" just ruins it...

Speedy recover to the nutty bastard though. Kinda looked like he was bouncing off concrete when he dived forward there...

Hmm... Never seen light move that slowly as it bounces off objects. Do clouds possess some type of magic, other-worldly temporal physics in the reality in which your crazy, tinfoil-hat-wearing brain resides?

Curious minds want to know!

I've seen ball lightning, or something that seemed terribly similar to the descriptions, once. As a wild, midwestern thunderstorm was rapidly approaching, there were two glowing balls around 3-4 foot in diameter "bouncing" along above a set of power lines. They lasted just a few seconds, fizzling out about the time the rain hit.

Indeed, his sparring partner didn't seem to be bouncing back to his feet did he?
