Why it's dangerous
When ingested, the glue reacts with stomach acid and rapidly expands into a large, firm foam mass, causing a foreign body obstruction in the gastrointestinal tract.
Toxic compound: diisocyanate
Good to know
The glue expands significantly upon contact with moisture in the stomach, creating a life-threatening blockage that cannot be passed naturally.
