We've all been there.
You're sat at home with a friend and nothing to do so you decide to have a little fun.
These two guys sat on a rug and rubbed their feet on it vigorously, while holding a light bulb in their hands.
They then joined their fingers together and were surprised to see the bulb light up because of the static electricity in their bodies.
You can see their Eureka! moment in the video above.
