Magna-Tiles
Safe geometric magnetic builders. The magnets are ultrasonically welded inside plastic encasements vastly larger than a child's airway.

The quick answer
The CPSC has issued sweeping warnings and recalls regarding small, high-powered neodymium magnet sets. If a toddler swallows two separate magnets, those magnets will aggressively attract to one another across different loops of the intestine, clamping the tissue between them. This causes catastrophic bowel perforations, tissue death, and sepsis. All "loose" rare-earth magnet toys must be completely eradicated from homes with small children.

01
The Anatomy of a Magnet Ingestion
High-powered neodymium magnets, the small rare-earth sets covered by CPSC recalls and warnings, are 10 to 50 times stronger than standard refrigerator magnets. Parents mistakenly assume a swallowed magnet will just "pass through" like a penny.
But if a child swallows one magnet on Monday, and another on Tuesday, they travel through the twisting maze of the intestines at different speeds. When the two magnets get close to each other, their immense strength pulls them together, ripping right through the intestinal walls to connect. This is a life-threatening surgical emergency.
High-powered neodymium magnets are 10 to 50 times stronger than refrigerator magnets, and swallowing just two can clamp loops of a child's intestine together and tear through the tissue.
In short
- Swallowing multiple magnets causes them to clamp the intestines together.
- Bowel perforations are frequently fatal if not caught immediately.
The bottom line
Audit your older children's toys and any "desk toys" belonging to adults. Magna-Tiles are generally safe because the magnets are severely encapsulated in massive plastic tiles, but tiny Buckyballs or loose magnetic beads are lethal.
