Who knows what props are used in the big bang magic! !

Actually, this is a prop. You put the light bulb in a bag, and then seal the mouth of the bag with a clip to ensure that the light bulb is not disturbed. But the problem is the clip. This clip has a very thin iron bar. As long as the clip is opened and closed manually, the iron bar will pop out quickly. The iron bar was strong enough to numb your hand, so I was beaten. So it's okay to smash a light bulb. It is a clip in front of your eyes.
