What is the science behind magnetic slime?
The magnet is very strong but something prevents the iron filings from leaving the slime and clinging to the magnet. The slime holds onto the iron filings by adhesion. Adhesion is a force that holds molecules of different substances together. In addition to adhesion, the slime polymer is bonded by cohesion.
