A bottle filled with ethanol vapor is ignited. This results in a loud 'whoosh'.

im so happy that you came back alive!

Keep on with your fascinating experiments.

good to see you back at it hope to see more soon :)

Put a harmonica in front of it

That last one makes me wonder what would happen if the bottle was spinning making the alcohol stay moving inside. I bet youd have a much more violent/efficient burn

[@bharrison4]

glad your back!

This demonstrates how changing the size and shape of the bottle changes the sound and speed of the reaction.

Nice bong you got there.

Hey..just for those who try in winter outside...no ignition will take place with at least with 70percent alcohol. Not one video on alcohol rockets or whoosh bottles mentions this ...but I just found out today. :)..the flash point is much higher..around 50 degrees.

Same thing will happen if you take an empty soda can and hold the button down on a bic so it fills with butane and then light the lighter and it does the same thing. Be carefull tho because when i did it i burnt the shit out of my thumb resulting in a huge blister

If you absolutely must try this at home, make sure you own the house or your rental agreement allows open flames on the property. Also, only do this outdoors.

how milliliters need for each ignition?

Why hydrogen gas doesn't explode in a flask

[@nishumurmu2404]

it's application? ?

Does the ER pay for these videos?

[@nandgarg]

what is the reason behind it????

[@smoolae5474]

DR.NANDKUMAR Garg Alcohol vapors mix with air and after lightning it an exothermic reaction takes place. The confined space of the vessel and the rapidness of the combustion promote the “whoosh” sound occurring during the reaction. But when there is something wrong with the ratio You will probably end up with just burning alcohol flame (too much alcohol vapor) or with loud bang and with no flame or "whoosh" (air and alc.vapor ratio suitable for an explosion).
