Why do champagne bottles pop

Yes, that's fast for a cork even if it has a small mass. What would New Year's Eve be like without explosives? These tiny party poppers have just enough explosives to shoot some streamers out of a small container.

Here is a plot of the position of a streamer as it comes out of the popper. The streamers leave with a velocity of about But notice how the slope of the position graph decreases towards the end. The streamers slow down because of air resistance. At the beginning of the shot out of the popper, all of the streamers are bunched up together making them sort of like one larger object with a larger mass.

As they spread out, the ratio of air resistance to mass increases and they start to slow down. I guess this is all for the best. If the streamers continued on with a high initial speed, they would fly all the way across the room. Although the sound might be rather annoying, these party horns show some cool physics. The horn sound comes a vibrating plastic part in the mouth piece.

It might look something like this. The small plastic piece contains two flaps that are pushed closed. To avoid a massive eruption of foam—and to save someone around you from being injured accidentally—you should always twist the cork from the bottle into your hand.

After removing the foil and releasing the cork from its metal cage, grasp the cork in one hand and keep the other hand firmly on the base of the bottle. Keep the bottle at a 45 degree angle steadied and twist the cork slowly into your palm. The cork should be gently and soundlessly released into your hand—with no spray or mess to mop up. Keeping your thumb over the cork while you open the bottle will prevent the cork from accidentally shooting out, and give you more control over the cork as you remove it.

It will also make it less likely that someone around you will be injured by a flying cork of death. Unless you enjoy warm, flat Champagne, your bottle should always be chilled before serving. The optimal temperature for any sparkling wine is 47 to 50 degrees Fahrenheit. At this temperature the wine is likely to have crisper, tighter bubbles, and the best aroma and taste. But never, ever, ever put your Champagne bottle in the freezer to chill—unless you want an explosion of thick, gnarly, extremely sharp glass in your kitchen.

I suppose if one were to try and reduce the risk of eye injury due to champagne cork impalements, I would suggest making sure the temperature of the wine was as cold as possible. That means there is a ton of energy not accounted for in this study. The authors suggest, and I tend to agree, that the majority of the energy in the cork popping process is transferred to sound energy—i.

Further tests would be needed to determine how much energy is converted to sound energy, and how any remaining energy is converted. In addition to reducing eye injuries, this study could have potential implications for the development of better corks, cages, or even champagne bottles, but certainly there are no conclusions about any of this that can be made based on the particular experiments performed.
