use the steel wool to complete the circuit on a 9 volt battery. Touch it to both ends of the battery at once and it will spark, have kindling nearby to be lit by the steel wool.
Putting steel wool on a battery connects the two terminals of the battery, causing electrons to flow through the steel wool. This makes sparks fly out of the steel wool, which heats up rather quickly. it is one way to start a fire as the steel wool will get red hot and burn you or start a fire
it catches fire
Focusing light. Striking flint
Not sure
Electricity is energy. Energy can be different things. We have movement as an energy, kinetic energy that is. Then there is, amongst others heat, as an energy. Electricity must be in a circuit to work. When putting the 9volt battery in the steel wool you make a circuit. Then the electricity will flow through the steel wool. When the electricity is not being used by anything (no light bulbs or anything), it is being converted to heat energy. Steel wool burns easily, so the heat will easily ignite the steel wool.
catches on fire
Steel wool.
The steel wool turns blue after burned. The mass also increases.
thin steel wool
steel wool is steel made from wool, so it would be neither
the wool does not rust
steel wool burns in oxegen and produces heat and light
