The paper spiral is turning due to convection currents created by the heat from the Bunsen burner. As the air surrounding the spiral heats up, it becomes less dense and rises. This rising hot air creates a flow pattern that causes the spiral to rotate.
the gas from the Bunsen burner will cause the existing flame to flare and burn the entire piece of paper and your fingers - and the lab. it's difficult to blow out the burning paper.
In a paper spiral, energy is transferred in the form of mechanical energy as the paper spiral unwinds and falls due to gravity. This mechanical energy is converted into kinetic energy as the spiral moves.
When hot water is applied to a paper spiral, it weakens the bonds between the paper fibers, making the paper expand and contract unevenly. This uneven expansion and contraction causes the paper to twist and move in a spiral motion due to the differences in tension along its length.
When heat is applied to one side of the paper, it causes uneven expansion of the paper, resulting in one side expanding more than the other. This imbalance in expansion causes the paper to curl or spiral as it tries to relieve the stress.
When the heat was turned off, the paper spiral would cool down and contract in size as it loses thermal energy. The expansion and contraction of the paper spiral are due to changes in temperature, causing its fibers to either expand or contract, leading to a change in its overall size.
No, it is not safe to light a Bunsen burner with burning paper as the paper may not provide a consistent flame and could introduce contaminants to the burner. It is recommended to use a striker or a lighter to ignite the Bunsen burner's gas flame.
No, it is not safe to use paper to light a Bunsen burner. Paper can easily catch fire and burn rapidly, posing a safety hazard. It is better to use a proper ignition source like a match or a lighter to light a Bunsen burner.

Paper has a low ignition temperature, so it may burn too quickly and not sustain a flame long enough to light a Bunsen burner. Additionally, paper may produce ashes or residue that can clog the burner's openings. It's safer and more effective to use a lighter or matches to ignite a Bunsen burner.
No, it is not safe to light a Bunsen burner with a burning piece of paper because it can lead to an uncontrolled flame and potential accidents. It is recommended to use a striker or a lighter specifically designed for lighting Bunsen burners to ensure proper control of the flame.
The spinning motion of the paper snake when held over a Bunsen burner is due to convection currents created by the heat rising from the flame. As the air above the flame gets hot, it rises creating a low-pressure area that causes the paper snake to rotate. This is a demonstration of the principle of convection.
I prefer a number-two pencil and sheet of fine copier paper when drawing pictures of laboratory equipment. But the technique is pretty simple: you either get a Bunsen burner from the lab, or download a photo of one from the Internet, and sketch it.
Using a piece of burning paper could potentially cause the flames to travel back to your hand when trying to light a Bunsen burner. It is safer to use a mechanical striker or a lighter designed for lighting Bunsen burners to prevent accidents.

The lined paper is smaller lines and the spiral is bigger lines
When you hold a spiral paper over a lit candle, the heat causes the air within the spiral to rise, creating a mini updraft that makes the spiral rotate. The rotation is caused by the temperature difference between the inside and outside of the spiral paper.
The paper spiral turns due to the heat rising (thermal) from below. Once the heat is turned off, there is no longer a thermal to turn the spiral, so the spiral ceases to turn.
