In this insane high-voltage experiment, we connected a toy figure to a power supply running 50. 4 volts, and the result was shocking — the toy's hair ignites in a burst of flames! Surrounded by smoke and lined up AA batteries, this setup turns a playful scene into a fire hazard.

Solar panels convert sunlight into electricity through the photovoltaic effect. Photons from sunlight hit silicon cells inside the panel, knock electrons free from their atoms, and an electric field pushes those electrons through a circuit — that flow of electrons is electricity.

After harnessing solar energy through photovoltaic panels, homeowners and businesses have the option to sell surplus electricity back to the grid. This practice, known as net metering, enables solar panel owners to earn credits or payments for the energy they contribute to the grid.
