What happens to a cluster of grapes when it’s in between two large, very strong and potentially dangerous neodymium magnets as they collide? Science presenter Kevin Delaney and his team demonstrate the power of these rare-earth magnets with a ‘crushing device’ in this rowdy clip from the television show Street Science on The Science Channel.

As they say on television: Don’t try this at home. Magnets of this strength can pinch, crush, break, or injure anything or anyone in their way. As you can see in the clip, the team is wearing safety gear to protect their bodies from the magnets and any shattered materials from the collision. Knowing these neodymium magnet hazards can help with practicing safe & smart science.
