Burning a candle next to a glass of water can create a visually interesting effect and serve a practical purpose. The heat from the candle melts the wax and produces vapor, while the flame consumes oxygen, leading to a decrease in air pressure inside the glass. If the flame goes out, the cooling air inside the glass creates a vacuum that can draw water up into the glass, demonstrating principles of air pressure and atmospheric science. This simple experiment can be a fun way to explore concepts in physics and chemistry.

How do you put out a candle without smoke?

you could get it wet but it will ruin the candle or you could use honey put a little dab on the candle and it will go out the next time you lite it the honey will burn off you could get it wet but it will ruin the candle or you could use honey put a little dab on the candle and it will go out the next time you lite it the honey will burn off


How do you get your three wick candle to burn even?

Remove some wax and re-burn the candle to level out the wax melt. When the candle wax is solid, carve out a "moat" from the wax, around the circumference of the candle, by running a knife (or spoon) around the edge of the glass. Depending on how short your wicks have gotten, make your moat about 1/2" deep by 1/2" wide (for a 4" diameter candle). It doesn't have to be pretty; it'll all smooth out when re-burning. Next, scoop out the wax berms between the three wicks and in the middle of the candle. Depending on how shallow your wicks have gotten, you could go 1/4" to 1/2" deep here. Then relight the candle and let it burn for several hours until the wax has re-leveled itself. You can help it along by gently tilting the candle in a circle after about an hour of burn time. Repeat as needed.


How can you prove that air exist?

Ask the person, What do we breathe? For an actually experiment; Light a candle, the oxygen in the air keeps it going. Now do the same in space with no air or oxygen - no flame. Conclusion: air exists on Earth.</ If you fill your tub with water, then, crush a small peice of paper and tape it to the bottom inside of the cup. Slowly, put the cup in the water and you should see that the cup has no water in it and the paper is dry. unless you dip the cup in the water and scoop it up, but you arent supposed to do that.


Where does the wax go when you burn a candle?

The wax of the candle and some oxygen in the air are converted into some carbon soot, water vapor, some complex hydrocarbons in the smoke, and carbon dioxide. If you stand a small candle on a saucer and cover it with a tall glass, you can see each of these things. The candle will burn the oxygen in the glass. You will see the carbon dioxide and smoke fill the bottom of the glass. You will see a little water condense on the side of the glass, and the top of the glass will be blackened with the soot. When the level of smoke and CO2 reach the level of the flame, the candle will go out.

Why do some candles burn down so quickly?

A candle will burn faster at room temp. Candels burn by means of the wick effect. The energy from the flam heats the wax beneath the wick ( by way of convection threw the wick and by luminescent radiation , causing it to melt then asend threw the wick, ( eventually having enough heat to evaporate buy the time it reaches the top of the wick) It then burns as a vapor when mixed with oxgene much like gasoline, the melting and vaporisation points vary depending on the type of wax used, but ultimitly the warmer the candel to begin with the faster it will burn.

What earth process would it be if you put your hand next to a candle flame it doesnt really hurt but if you put your hand directly above the flame you burn yourself?

The process of heat rising would be the earth process in force if a candle is touched on the side and it is cooler than a hand over the candle. The hand over the candle will get burned because of the direction of the heat of the flame.


How do you flip a glass of water without spilling it?

simple. place a piece of paper that is a little larger than the circumference of the glass on top of the glass. The next step is to flip it over completely with a good speed. not too fast though... after this you will observe a glass of water that is completely upside-down and it won't be spilling if you used the right paper. *this will be most effective if the glass of water is completely full*

Why do candles go out when we put glass jars over them?

Oh, dude, it's like, science and stuff. So, when you put a glass jar over a candle, it messes with the oxygen flow that the flame needs to keep burning. It's like trying to breathe with a plastic bag over your head - not a good idea if you want to stay alive, you know? So yeah, candles need oxygen to burn, and glass jars are like, "Nope, not today, candle."


What color candles burn faster?

It always depends on the size and shape of the candle. The rate at which a candle burns is dependent on the size and composition of the wick, and the thickness, composition, and melting / vaporization rate of the candle wax. Color is not the predominant factor.Other observations* It's not the color of the candle, but the wick. If the wick is cheap the candle won't burn correctly or will burn out shortly after you light it. If the wick is of good quality, it will burn down the center of the candle without once going out.* Candles that are plain (white) may burn faster because they don't contain as many chemicals in the wax.* There is a good reason why one candle burns faster than another... because it takes less time to vaporize the wax.* The color would only make a difference in that respect if a significant amount of the heat (imparted on the wax) came from the flame's infrared radiation. Because the wax is used up by being heated by the flame (and eventually being melted, vaporized, and then combusted), the composition of the wax and wick will have more consequence than how much light energy the wax absorbs or reflects.
