Super strong magnets

We bought these for a science experiment to see how temperature affects magnet strength. My son had a blast playing with the magnets. They are incredibly strong, so strong that he was afraid to have his fingers close when the magnets came together by their own strength since they snapped together quite forcefully. Definitely strong and as described.
