How do you make a circuit without a light bulb holder?

To make a circuit without a light bulb holder, you can connect the light bulb directly to the wires by using alligator clips or by twisting the exposed ends of the wires around the metal base of the bulb. Ensure that the circuit includes a power source, such as a battery, and that the connections are secure to allow for a complete circuit. Be cautious to avoid touching the bulb's glass while the circuit is powered, as it can get hot. Additionally, make sure the circuit is properly insulated to prevent short-circuits or electrical hazards.
