"Hazardous Magnetic-Ball Kits Recalled by Federal Agency from Walmart.com"

TL;DR
The U.S. Consumer Product Safety Commission has issued a recall for the Relax 5mm Science Kit, which contains hazardous magnetic balls sold at Walmart.com. These magnets exceed federal standards for magnetic strength and pose a serious ingestion risk to children, potentially causing severe internal damage or death. No injuries from this product have been reported, but there have been cases of magnet ingestions leading to hospital visits and deaths in the past. The kits, distributed by Joybuy Marketplace Express, have been removed from Walmart's website.
