Put a sheet of aluminum foil in boiling water

Some claim that boiling a crumpled piece of aluminum foil in water can help dislodge stuck-on grime in pots or pans by acting as a mild abrasive or helping loosen residue. However, this effect is minor compared to soaking with dish soap or using vinegar and baking soda.

⚠️ Important Notes
Don’t ingest or cook food with disintegrated foil pieces.

Never microwave aluminum foil.

This does not purify water, remove toxins, or provide health benefits.

Conclusion:
Yes, some people—rich or not—use aluminum foil in boiling water, but usually for silver cleaning, not magic tricks. The phrase “seeing is believing” probably refers to the surprisingly good results of this specific chemical reaction.
