Bottles on Fire
This is an old technique I used to play when I was little in the Boy Scouts, but now with my DSLR i`ve got impressed.
Basically the main idea is to let the alcohol inside the bottle vaporize, and then turn it on, so you can take the picture.
In the next days ill take more pictures with different bottles, I promise to upload.
Camera: Sony DSLR-A300
Focal Length: 50 mm
ISO Speed: 800
Exposure Bias: 0 EV

You need an empty glass bottle. Then you put a little bit of alcohol inside and shake it with the cap on so the alcohol get vaporized in the inside, after that take the cap off and very fast put a lightened match in the top of the bottle, so a big flame will blow out (Be careful!!!). And with a remote control take the pictured for at least 2 o 3 seconds.
PS: Sorry for my poor English but im trying my best.

sounds highly dangerous, but the pictures turn out really well especially the first one where the bottle is almost fully lit up in blue and you can see the swirling motion of the gasses.

ha ha, i remember doing this when i was in middle school, except we used lighters. We just turned the lighter on and it let the gas into the bottle. Course when we where showing off, we'd actually poor the gas into a closed hand, then right as we ignited it, we'd open our hand up and it would look like you had a fireball on your hand. Fortunately, non of us ever got hurt.
Back to the subject at hand, Very cool shots!

If you use 70% alcohol, it will burn slower and less hot than 90%. Also, you can use cotton swabs soaked in the alcohol attached to a wooden stick like a chop stick, you can use it to extend your distance from the top of the bottle. It's a technique used in what's called fire cupping. Keep water and water soaked towels close at hand to extinguish any unwanted fires.
Very cool effect though. Can't wait to see more!

Your english is improving well! A question, did you burn/paint the background right up to the bottle? Because you may want to pull off just a little bit.Otherwise the picture is awesome!! I want to try that sometime."One should really use the camera as though tomorrow you'd be stricken blind."

If you’re going to try, go for it, but my best tips beside for being very careful , its to empty very well the bottles after each time you burn the oxygen in the inside, my technique is fill the bottle (after the picture) with water and empty them, now you’re ready to do it again.
Good luck, and share you pics!!!
