Learn how to make your own ferrofluid and discover how it works
Looking for a cool science experiment you can do at home? Look no further! Ferrofluid, or ferripaste, is an easy, fun-to-make magnetic oil that only needs 2 ingredients: motor oil and iron oxide powder. When you mix these 2 things together, it creates a special “fluid” that almost behaves like a solid, especially in the presence of a magnet. So what are you waiting for? To make your very own ferrofluid to play around with, read this article!
Things You Should Know
- Mix 10 grams (0.3 oz) of motor oil with 10 grams (0.3 oz) of iron oxide powder in a petri dish .
- Use a magnet to manipulate the ferrofluid to make peaks and valleys.
- Because the iron oxide is magnetic and suspended in the oil, a magnet can manipulate it.
- Store ferrofluid in an airtight container. When you’re done, dispose of the ferrofluid in the trash.

Warnings
- Iron oxide will stain clothes and surfaces. Be careful not to get it on your clothing or countertops during your experiment. [8] X Research sourceThanks
- Ferrofluid is highly flammable, and while it’s not toxic, it can cause skin irritation. If ferrofluid gets on your skin, rinse well with warm water for 15 minutes. [9] X Research sourceThanks
