the candle light turns off when the cup is placed over the candle and water rushes in due to atmospheric pressure . when cup is placed on the candle all the air goes out and the glass lifts up due to the atmospheric pressure releases from outside of the cup as there is no air inside to balance the pressure exerted out of the cup . thus when the glass lifts up and the water gets into the cup .
Depends on the size of the cup.
You have to melt wax on the stove. Get a cup, ( about 3, or 4 inches tall). Get a crayon, and the candle. For this the candle has to be mini. break up the crayon (about 1 inch a piece), put them in the cup. Then put wax in the cup with the crayon and stir until all the chuncks of crayon are gone. The wax will be the same color as the crayon. Then sit the mini-candle n the cup of colored wax. DONT TAKE THE CANDLE OUT!!! Leave the candle in there and it stays in there cuz that is the candle. when it all drys you can decorate it with sparkels and other things.
There are 8 fluid ounces in 1 cup. To find out how many 1 cup candle molds Vicky can fill with 144 fluid ounces of candle wax, divide 144 by 8. This calculation gives 18, so Vicky can fill 18 one-cup candle molds with her recipe.
There are many ideas for candle wedding favors. Examples of ideas for candle wedding favors includes custom candles, beautiful candle holders, and small candle sticks.
Since there are 8 fluid ounces in 1 cup, Vickie can fill 18 one-cup candle molds with her 144 fluid ounces of scented candle wax (144 divided by 8 equals 18).
If burning, the candle will use up all the oxygen and go out.
On the Red Bucket/cup
This is known as an experiment demonstrating the concept of water displacement and the principle of atmospheric pressure. When the candle burns inside the cup, it consumes oxygen, reducing air pressure inside the cup. The higher atmospheric pressure outside the cup forces the water up into the cup to balance the pressure difference.
If you know the basic effect that fire feeds on oxygen it would be easier for you to understand. when the cup covers over the candle, candle flame takes all oxygen inside the cup away, and something needs to be replacing that oxygen, therefore water goes into place
If you cover a burning candle with a glass cup and surround it with water, the flame will eventually go out due to lack of oxygen inside the glass cup. The water surrounding the cup may help dissipate the heat generated by the candle, but it will not affect the flame itself unless the water somehow extinguishes it. It's important to exercise caution when attempting such experiments to avoid accidents.
The candle burning is a chemical process.
