It's so cool! I use them to remove stirrers from bottles and beakers in the lab. I've also used them as a replacement for extremely expensive PCR tube racks that pull magnetic beads through tiny bits of liquid. Even though. I ended up just buying an expensive rack as this workaround required a lot of effort and I had to use this method regularly. Still a fantastic magnet! Also a funny note. Don't leave it around picky people. They tend to grab them and hurt their hands while playing with these magnets. Of course, only let children use it under supervision.
